Question

can the sum of n terms in an ap is 2n + 13 and justify your answer ​

Answer 1

Answer:

15,17,19,21

Step-by-step explanation:

As n can be any natural number

we start bro 1 and go on

if we put the value of n 1,2,3......

we get an ap of common difference 2

Answer 2

Answer:

Given that,

nth term =2n+13

replace n by natural numbers.

→2(1)+13=2+13=15

→2(2)+13=4+13=17

→2(3)+13=6+13=19.....

the list of numbers form an AP.

15,17,19,...........

First term(a)=15

common difference (d)=2

I say the sum of n terms can be in the form 2n+13.
