Sum of Arithmetic Sequence a = 7, n=79, and d=1 is 3634.0

Steps to find sum of n terms of arithmetic sequence:

sum of n terms of arithmetic sequence formula:-

Sn = `n/2 (2a+(n-1)d)`

where:

  • sn is the sum of n terms
  • a is first term
  • n is total number of terms
  • d is common difference

Input values are:-

a = 7

n = 79

d = 1

Put values into formula

S79 = `n/2 (2a+(n−1)d)`

S79 = `79/2 * ( 2*7 + ( 79 - 1)*1 )`

S79 = 3634.0

Here is the detailed procedure to find the sum of first n terms of Arithmetic Sequence a = 7, n=79, and d=1. Let’s jump into the process and learn the calculation along with the output of sum of n terms of AP:

  • At first, we need to figure out the given values to find the sum of first n terms of AP ie., a = 7, n=79, and d=1.

  • Now, take the sum of n terms of Arithmetic progression formula ie., S = n/2 * [2a₁ + (n-1)d] and substitute the input values.

  • After that, we get S = 79/2 * [2(7) + (79-1)1].

  • Now, simply the above expression to get the sum of first n terms of Arithmetic sequence for a = 7, n=79, and d=1 is S5 = 3634.0
