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

Answer» First four terms of an `AP` can be given as,
`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`
