The first term of an A.P is equal one-half of the common difference,d, find the 8th term of the A.P in the tern of 'd'
Answered by Bosnian
a1 = first term of A.P

d = common difference

an = nth term of A.P

an = a1 + ( n - 1 ) d

The first term of an A.P is equal one-half of the common difference means:

a1 = d / 2

In tis case:

a8 = a1 + ( 8 - 1 ) d

a8 = a1 + 7 d

a8 = d / 2 + 7 d

a8 = d / 2 + 14 d / 2

a8 = 15 / 2 d
