Find the Sum of n terms of Arithmetic Sequence a = 5, n=75, and d=1

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 = 5

n = 75

d = 1

Put values into formula

S₇₅ = `n/2 (2a+(n−1)d)`

S₇₅ = `75/2 * ( 2*5 + ( 75 - 1)*1 )`

S₇₅ = 3150.0

Here is the detailed procedure to find the sum of first n terms of Arithmetic Sequence a = 5, n=75, 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 = 5, n=75, 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 = 75/2 * [2(5) + (75-1)1].

• Now, simply the above expression to get the sum of first n terms of Arithmetic sequence for a = 5, n=75, and d=1 is S₅ = 3150.0
