Math CentralQuandaries & Queries


Question from Kyle, a parent:

What number comes next in the series 49,48,46,43,39...?

look at the difference between consecutive terms in the series:

start at 49, then subtract 1 and
you get 48, then subtract 2 and
you get 46, then subtract 3 and
you get 43, etc.
