### Steps to find sum of n terms of arithmetic sequence:

sum of n terms of arithmetic sequence formula:-

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 = 10

n = 78

d = 1

Put values into formula

S78 = n/2 (2a+(n−1)d)

S78 = 78/2 * ( 2*10 + ( 78 - 1)*1 )

S78 = 3783.0

## Step by Step Process for Finding Sum of n terms of Arithmetic Sequence a = 10, n=78, and d=1

Here is the detailed procedure to find the sum of first n terms of Arithmetic Sequence a = 10, n=78, 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 = 10, n=78, 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 = 78/2 * [2(10) + (78-1)1].

• Now, simply the above expression to get the sum of first n terms of Arithmetic sequence for a = 10, n=78, and d=1 is S5 = 3783.0
