Write first four terms of the AP, when the first term a and the common difference d are given as follows:(i) a = 10, d= 10

(ii) a = –2, d = 0

(iii) a = 4, d = – 3

(iv) a = – 1, d = 1/2

(v) a = – 1.25, d = – 0.25

$a,a+d,a+2d,a+3d$

Here,$a=10$ and $d=10$

So, first four terms are = $10,(10+10),(10+2(10)),(10+3(10))=10,20,30,40$
