Find the Sum of n terms of Arithmetic Sequence a = 2, n=71, and d=2

Steps to find sum of n terms of arithmetic sequence:

sum of n terms of arithmetic sequence formula:-

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

where:

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

Input values are:-

a = 2

n = 71

d = 2

Put values into formula

S₇₁ = `n/2 (2a+(n−1)d)`

S₇₁ = `71/2 * ( 2*2 + ( 71 - 1)*2 )`

S₇₁ = 5112.0

Here is the detailed procedure to find the sum of first n terms of Arithmetic Sequence a = 2, n=71, and d=2. 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 = 2, n=71, and d=2.

• 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 = 71/2 * [2(2) + (71-1)2].

• Now, simply the above expression to get the sum of first n terms of Arithmetic sequence for a = 2, n=71, and d=2 is S₅ = 5112.0
