Question

Given the sequence 2,5,8,11....,at what nth term will the number become 32?

A.9th term. B.10th term. C.11th term

D.12th term

Answer 1

As the sequence 2,5,8,11 is an AP because

Common difference (d)= 5–2=8–5=11–8= 3

Here, first term(a) = 2

No. of terms(n) = 10

Then, as we know,

nth term = a+(n-1)d

Hence, 11th term = 2+(10–1)3 = 2+ 9×3= 29 Ans.
