Question

find the first four terms of an AP whose first term is -2 and common difference is -2

Answer 1

First trm=-2
Common difference=-2
Therefore terms are
A,a+d,a+2d,a+3d
-2,-4,-6,-8

Answer 2

First terms of an A.P whose first term is -2nd common difference is -2

a1= – 2,

a2= a1 + d = – 2 + (– 2) = – 4

a3 = a2 + d = – 4 + (– 2) = – 6

a4= a3 + d = – 6 + (– 2) = – 8

First four terms are – 2, – 4, – 6, – 8
