First column header is called AGE and the second column header is called Age_Group.

Answer 1

As the idea of a Table was causing some confusion I thought I would also share my favourite trick of a self contained, table free, VLOOKUP using an embedded array. So for the current problem it would look something like this:

VLOOKUP(A1, {18,"18-24";25,"25-29";30,"30-35";36,"36-37"}, 2 TRUE)
