Question

Write the value of a₃₀ − a₁₀ for the A.P. 4, 9, 14, 19, ....

Answer 1

In this problem, we are given an A.P. and we need to find.

A.P. is

Here,

First term (a) = 4

Common difference of the A.P. (d)

Now, as we know,

Here, we find a₃₀ and a₂₀.

So, for 30^th term,

Also, for 10^th term,

So,

Therefore, for the given A.P.
