is your answer look it once
I think its multiplying im gonna say 144
Which sequence is arithmetic? 6, 12, 15, 21, ... 7, 14, 21, 36, ... 8, 16, 32, 64, ... 9, 18, 27, 36, ...
charle [14.2K]
9, 18, 27, 36 is a Arithmetic sequence and the sequence is 9
-0.5 and 2 the difference is 2.5. 2.5 times 4 equals 10. 2 and -8 the difference is 10. 10 times 4 equals 40. -8 and 32 the difference is 40
