Students will first review the definition of summing before learning the formulas for summation. The cumulative total of terms in a sequence is referred to as a summation (or sum). Instead of manually expressing the entire sum, we use the summation notation to represent the sum of more terms—say let’s n terms—in a sequence called “an.” Specifically, a1 + a2 +. . . + an =
∑ni =1ai. Let’s use a few solved instances to master the Summation Formula and their uses.
Utilising CBSE study resources is normally a wise choice while getting ready for a test. The student’s understanding is increased, and their subject knowledge is increased. Utilising CBSE study materials helps students learn more effectively. Only the NCERT texts may be used in educational contexts. It is advised for students in grades 1 through 12 to organize their study resources by subject. It is adequate to study from the NCERT book for the specific subject, while students are advised to use the CBSE Study Materials once they have finished the NCERT books for their courses.
Students can get the Summation Formula on the Extramarks website and mobile app. The Joint Entrance Exam and other competitive exams are relatively easy for pupils to take thanks to this curriculum (JEE). If a student is interested in applying to the Indian Institutes of Technology (IITs) or National Institutes of Technology (NITs), use Summation Formula to gain a fundamental understanding of the subject. Students can take competitive tests like the Central Universities Entrance Tests to pursue vocations other than engineering (CUET). Because MCQs may be present in certain exams, understanding the Summation Formula can help students learn the content more effectively.
The Summation Formula on Extramarks is a fantastic resource for exam preparation. Students may utilize the Summation Formula to better understand the various question types that may be included in the annual exam. The Summation Formula will aid students in understanding the key concepts and subjects that frequently appear on board exams. These suggestions can help students focus and respond to more test questions. To excel in Mathematics, students must be able to memorize and recall a variety of theoretical ideas. It could be challenging for students to remember all the concepts. Students sometimes forget the topics they already know when learning new ones.
What Are Summation Formulas?
The sum of the series is computed using the Summation Formula. There are many different kinds of sequences, including arithmetic and geometric sequences, and consequently, there are many different kinds of Summation Formulas for those different kinds of sequences. There is also a Summation Formula that determines the sum of natural numbers, the sum of natural number squares, the sum of natural number cubes, the sum of natural number evens, the sum of natural number odds, etc. The list of Summation Formula is provided here. Each of these formulas will be covered in detail in the section that follows.
Every possible educational need that a student can have is met by Extramarks. Despite the fact that NCERT books are such an effective source of educational information, students still worry about finding reliable Summation Formulas. NCERT Solutions from Extramarks are precise and thorough. It also provides a whole educational solution that blends the advantages of actual classrooms with study aids to foster a productive learning environment for pupils. The Summation Formula has a PDF version. Students must have access to the Taylor Series Formula.
List of Summation Formulas
Students are aware that the outcome of adding two numbers is their sum. So, if the sequence x1 + x2 +. . . + xn = ∑ni =1xi exists, the sum of its terms is represented by the symbol ∑ (sigma). i.e., the total of the preceding order ∑ni =1xi = x1 + x2 +. . . + xn. The expression ∑ni =1 “sigma I is equal to 1 to n” can be read as “sigma I represent the sum of the terms of the sequence from the first term to the nth term” in this instance. However, finding the sum does not actually need us to constantly manually add the sum of the sequences. Instead, students employ the summation formulas listed below. These popular Summation Formulas are listed below.
Poor network connectivity and unforeseen network issues won’t be a hindrance to learning anymore. The professionally crafted Summation Formula contains all of the textbook’s problems, allowing students to study and get ready for tests.

A few of the learning modules and study tools available to students who want to do better on their exams are chapter-by-chapter worksheets and practice exams.
FAQs (Frequently Asked Questions)
1. What Are the Applications of the Summation Formula?
Without actually calculating the sum by hand, the summation formulas are used to compute the sum of any given series. As an illustration, n2 is the summation formula for calculating the sum of the first n odd numbers. This allows us to state that the first 30 odd numbers add up to 12 + 32 +… (30 numbers) = 302 = 900.
2. Does Extramarks make it simple for students to obtain the Summation Formula?
The website and mobile app for Extramarks provide students with quick access to the Summation Formula. The Summation Formula PDF file must be downloaded by students in order for them to fully comprehend it. Students will therefore be able to perform better in their next examinations.
