(ii) -
(iv) x + y, x - y, x - 3y,
(v) 2x – 3y, - 2x + 3y, - 6x + 9y, ..
Find the general term of the A.P. given by :
x + b, x + 3b, x + 5b,...​

Answer 1

Given,

A.P=0, -3, -6 . . . .

Here,

a=0

d=-3-0

=-3

4th term=-6+(-3)=-6-3=-9

5th term=-9+(-3)=-9-3=-12

6th term=-12+(-3)=-12-3=-15

7th term=-15+(-3)=-15-3=-18
