Answer 1

Answer:

Explanation:

First term of the AP is 5.

Common difference of the AP is (8-5) =3

The sum of AP is given by the formula=(n/2) (2a+(n-1) d).

Where,

n= number of terms.

a= first term.

d= common difference.

Sum of first 32 term is= (32/2)( (5×2) +(32-1) ×3) =16(10+93) =16×103=1648.
