Question

What is the next number in the series?
1/21   1/29   1/37   1/45   1/53   __?__

Quizplus · Accepted Answer

The pattern is to add 8 to the denominator (the bottom number in the fraction) each step.
1/21   1/29   1/37   1/45   1/53   __?__
1/(21 + 8) = 1/29  →  1/(29 + 8) = 1/37  →  1/(37 + 8) = 1/45  →  1/(45 + 8) = 1/53  →  1/(53 + 8) = 1/61
