#BTS: If this then … what?

This article was been published more than 6months ago. The information contained herein may be outdated.

If you’ve been reading my solutions and justifications for previous puzzles, this week’s puzzle should not pose any challenge:

If…
2=6
3=12
4=20
5= 30
6=42
Then…
9=?

 

Here, now, the solution to last week’s puzzle:

Once more, we have a puzzle involving order of operations. There are neither parentheses nor exponents, so we go right on to multiplications (7 * 7 = 49) and divisions (7 / 7 = 1). On to additions and subtractions, giving us the following final calculation: 7 + 1 + 49 -7, which equals 50.
