Question

if the nth term of an AP is an = 2n+3. find the common difference.​

Answer 1

$\large{\implies{Answer}}$

The first term

An=2n+3

A(1)= 2(1)+3=5

The second term

An=2n+3

A(2)=2(2)+3=7

The common difference

A(2)-A(1)=7-5

$\large{\implies{2}}$

Answer 2

Step-by-step explanation:

a2 = 2×2+3= 7

a2-a1= d

7-5= d

d=2

Common difference= 2
