If the nth term of an A.P. is 3n+2, find the sum of first 'n terms of that AP.​
alexdok [17]

Answer:

S_{n} = \frac{n}{2} (3n + 7)

Step-by-step explanation:

We require to find the first term a₁ and the common difference d

The n th term is given by 3n + 2, thus

a₁ = 3(1) + 2 = 3 + 2 = 5

a₂ = 3(2) + 2 = 6 + 2 = 8

d = 8 - 5 = 3

S_{n} = \frac{n}{2} [ 2a₁ + (n - 1)d ], substitute values

S_{n} = \frac{n}{2} [ (2 × 5) + 3(n - 1) ] = \frac{n}{2} (10 + 3n - 3) = \frac{n}{2} (3n + 7)
