Answer 2

Answer:

ANSWER

Given ,

First term =a=12

Let the common difference be d

and we know 7th term a

7 =a+6d and 11th term a 11

=a+10d

According to question a 11 −a 7 =24

a+10d−(a+6d)=24

a+10d−a−6d=2

4d=24

d=6

We know that,

20th term =a 20

=a+19d=12+19(6)=12+114=126

So , the 20th term of AP is 126.
