Question

The Netherlands term of an A.P is (2n+3) then it's n-3rd term is

Answer 1

Answer:

Correct option is

A

2

The common difference of an A.P. is given by a

n+1

−a

n

∴d=a

n+1

−a

n

=3+2(n+1)−(3+2n)

=2n+2−2n

=2

Hence, the common difference d=2

Step-by-step explanation:

hope its helps :)

Answer 2

Step-by-step explanation:

Solution:

Given that,

The nth term of an AP is:

a = 2n + 3

We have to find the third term a3

To find the third term, we have to substitute n = 3 in given formula

Plug in n = 3

therefore ... a3= 2 x 3 + 3

= 6+3

= 9
