The Problem
What are the next two numbers in this series? This is a purely arithmetic series.
30, 33, 42, 50, 55, 80, 88, 152, 162, 174, ?, ?
The Solution
202, 206. To figure out the next number in the series multiply each of the non-zero digits of the previous number and add them to that previous number.
