-2, 0, 2, 4
-2, 4, -8, 16
-2, -4, -6, -8
-2, -4, -8, -16

Answer 1

Answer:

-2 , -4 , -6, -8

Step-by-step explanation:

we know that :

a is first term = -2

d common difference = -2

: 2nd term-:

a + (n-1)d

= -2+(2-1)-2

= -4

: 3rd term-:

a + (n-1)d

= -2+(3-1)-2

= -6

:4th term

a + (n-1)d

= -2+(4-1)-2

= -8
