Question

Which term does not belong in this series?

64, 16, 4, 1, 1/2, 1/16
A) 1
B) 4
C) 16
D) 1/2

Answer 1

D) 1/2

Explanation:

The pattern shown in the sequence is that every number is divided by 4 (left to right) or multiplied by 4 (right to left). How did I get 4? I multiplied 64 by 16 (64/16) !

64 / 4 = 16

16 / 4 = 4

4 / 4 = 1

1 / 4 = 1/4 or 0.25 >> not 1/2 or 0.50!!

I hope this helps!!
