Question

If the first term of an A.P is equal to one half of the common difference d, find the eight term of the A. P.

Answer 1

Explanation:

The formula for Arithmatic Series is

`a_n=a_1+(n-1)d`

where a_1 and a_n are the first and n-th term of the series respectively,

d is the common difference of the series.

Now,

The eigth term is given by,

`a_8=(\frac{d}2)+(8-1)d=(15)/(2)d`
