Question

First four terms of an A.P. are ....., whose first term is -2 and common difference is -2.
(A) -2, 0, 2, 4
(B) -2, 4, -8, 16
(C) -2, -4, -6, -8
(D) -2, -4, -8, -16

Answer 1

Hey

Here is your answer,

A.P terms : a , a+d , a+2d , a+3d

First term, a = -2
Common difference , d = -2

a = -2
a+d = -2+(-2)
= -4
a+2d = (-2) + 2(-2)
= (-2) + (-4)
= -6
a+3d = (-2) + 3(-2)
= (-2) + (-6)
= -8

The correct option is (c) .

Hope it helps you

Answer 2

AP - a, a+d,a+2d,a+3d.........

therefore
a= -2
d= -2

the series will be

-2, -4, -6, -8

Ans: (C)
