Ais arithmetic because the common difference is -4. so:

2, -2, -6, -10, -14, -18, -22

B. is arithmetic because the common different is +6

-15, -9, -3, 3, 9

C. is geometric because the numbers divide by -2 each time

64, -32, 16, -8, 4, -2

Athe common difference is -4.

\(2, -2, -6, -10, -14, -18, -22\)

B. the common different is +6 

\(-15, -9, -3, 3, 9\)

C. the numbers divide by -2 each time 

\(64, -32, 16, -8, 4, -2\)
