Question

the nth term of an AP is given by an=3+4n. What is the cd?

Answer 1

Step-by-step explanation:

For the AP sequence, the nth term can be given by a(n)= a +(n-1)d ……….. (1) Where a is the first term and the

common difference is given by d.

an = 3+4n-4+4 = 7 +4(n-1) ………..(2)

On equating (1) and (2), we get a=7 and d=4
