Question

determine the 29th term of an AP. The 9th term of the series is -6 the common difference is 5/4

Answer 1

Answer:

Let the first term of the AP be a.

Common difference = d = 5/4

Given, ninth term = -6

So,

-6 = a+ (9-1) 5/4

-6 = a+ 10

a = -16

Now, 29th term = -16 + (29-1) 5/4

a(29th) = -16 + 35

a(29th) = 19
