Please help me with math

see below

Step-by-step explanation:

1) 4, -3, -10, -17,...

d = -3 - 4 = -7 or -10 - (-3) = -7

Arithmetic , d = -7

2) 4, 8, 16, 32,...

d = 8 - 4 = 4, 16 - 8 = 8,

d is not same

so Not Arithmetic

3) 7, 12, 17, 22,

d = 12 - 7 = 5 or 17 - 12 = 5 or 22 - 17 = 5

so Arithmetic, d = 5

step-by-step explanation:

if x = 2 you have to find x to finish the problem
