"IF" calculation for a range of numbers (not cells)

"A2" returns various numbers and I want "A3" to calculate based off of an "IF" statement - however, I cannot figure this out. I did look at the Excel Help and
tried different variations of the "comparison operators" to no avail.

IF A2 = 1-8, then value = 1
IF A2 = 9-16, then value = 2
IF A2 = 17-24, then value = 3

Thanks,

Maybe

=LOOKUP(A2,{0,9,17},{1,2,3})
