Question

what is the relationship between nth terms of AP and sum of the nth terms of AP

Answer 1

Answer:

Step-by-step explanation:

The sum of n terms of AP is the sum(addition) of first n terms of the arithmetic sequence. It is equal to n divided by 2 times the sum of twice the first term – 'a' and the product of the difference between second and first term-'d' also know as common difference, and (n-1), where n is numbers of terms to be added.

Answer 2

Answer:

nth terms of AP=a+(n-1)d

Sum of nth terms of AP=n/2{2a+(n-1)d}
