## Sum of Arithmetic Sequence a = 4, n=79, and d=5 is 15721.0

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 = 4

n = 79

d = 5

Put values into formula

S79 = n/2 (2a+(n−1)d)

S79 = 79/2 * ( 2*4 + ( 79 - 1)*5 )

S79 = 15721.0

Here is the detailed procedure to find the sum of first n terms of Arithmetic Sequence a = 4, n=79, and d=5. 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 = 4, n=79, and d=5.

• 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(4) + (79-1)5].

• Now, simply the above expression to get the sum of first n terms of Arithmetic sequence for a = 4, n=79, and d=5 is S5 = 15721.0
