Question

if SN is equal to 3n square + 2n then find the d​

Answer 1

Question: If S(n) = 2n² + 3n then, find the common difference (d) of the AP.

Answer: d = 4.

Note: • A sequence in which, the difference between the consecutive terms are same is called AP (Arithmetic Progression). • ...

Solution: It is given that ; S(n) = 2n² + 3n. Thus; ...

d = 4 .
