The 7th term of an A. P is '32' and its 13th term is 62. Find the A. P.

An = a+ (n-1)d

Now, a7= a+6d = 32(1)

a13= a+ 12d =62(2)

Subtracting (1) and (2)

-6d = (-30)

 d = 5

 Putting the value of 'd ' in (1)

a + 6 (5) = 32

a + 30 = 32

a = 32- 30

a = 2, d = 5

So, the required A.P is 2, 7, 12, 17,22

okay? wahts the question
