Question

The first term of an A.P. is p and its common difference is q. Find its 10th term.

 

Answer 1

Here, we are given,

First term (a) = p

Common difference (d) = q

 

We need to find the 10^th term (a_n).

As we know,

a_n = a + (n - 1) d

So, for 10^th term (n = 10), we get,

a₁₀ = p + ( 10 - 1 ) q

       = p + 9q 

Therefore,  a₁₀ = p + 9q
