Answer 2

$\huge\boxed{Answer}$

In A.P.

A(7) = a + 6d = 1/9

9a + 54d = 1 --------(1)

A(9) = a + 8d = 1/7

7a + 56d = 1

7a = 1 - 56d

a = (1 - 56d)/7

a = 1/7 - 8d -----(2)

From eq.(1) & eq. (2)

9( 1/7 - 8d ) + 54d = 1

9/7 - 72d + 54d = 1

9/7 - 18d = 1

18d = 9/7 - 1

18d = 2/7

9d = 1/7

d = 1/63

then , a = 1/7 - 8/63

a = 9/63 - 8/63

a = 1/63

Now , A(63) = a + 62d

= 1/63 + 62/63

= 63/63

= 1
