Question

If an=4n+1 then the find the first three terms of the AP​

Answer 1

Answer:

an=4n+1

Step-by-step explanation:

let n=1

a1=4×1+1

a=5

let n=2

a2=4×2+1

a2=9

let n=3

a3=4×3+1

a3=13

let n=4

a4=4×4+1

a4=17.

A.P=5,9,13,17.

Answer 2

Answer:

Soln:

Here,

an( nth term) = 4*n+1

Now,

First term(a1) = 4*1+1

= 5

Second term (a2) = 4*2+1

= 9

Third term (a3) = 4*3+1

=13

Therefore, the first three terms are 5,9 and 13.
