Answer 2

Answer:

Step-by-step explanation:

We have, an​=3n+2

Putting n=1,2 and 3, we get

a1​=3×1+2=3+2=5

a2​=3×2+2=6+2=8

a3​=3×3+2=9+2=11

Thus, the required first three terms of the sequence defined by an​=3n+2 are 5,8 and 11.

(ii) We have an​=n2+1

Putting n=1,2 and 3, we get

a1​=12+1=1+1=2,

a2​=22+1=4+1=5,

and, a3​=32+1=9+1=10.

Thus, the first three terms of the sequence defined by an​=n2+1 are 2,5 and 10
