Question

find an AP whose nth term is 2n+5​

Answer 1

Answer:

In order to determine the AP,

put values of n as natural numbers ie....

n=1,2,3,.....

when n=1,

2n+5=2(1)+5=7

hence,a=7

now,a2=2(2)+5=9

a3=2(3)+5=11

and so on...

so, the AP is 7,9,11,......

Answer 2

Step-by-step explanation:

Find the A.P. whose nth term is an = 2 – 5n
