How Would YOU Solve This ‘Brain Game’ In The February 2020 “Reader’s Digest”?

Full disclosure. I love mathematical puzzles like these. In my late teens & early 20s (way before there was an ‘online‘, never mind a Web) I used to buy IQ test books and do all the puzzles for fun. I still do them, though not that often anymore, albeit now on the Web. So, with this one I knew what I needed to be looking for.

Then I noticed something incongruous in a puzzle of this nature. There was a perfectly valid and obvious sequence for the numbers on the apex of the triangles: 2, 3, 4, 5 & 6.

But, I knew that that was TOO easy.

So, I worked out, quite quickly what the ‘pattern’ was. Pretty obvious from the first triangle. 8+3 = 11 & ’22’ is 11*2. Easy enough to validate that against the others.

So, as for the triangle in question. 8+9=17. 68÷17 –> –> wait for it. Wait for it. 68÷17= 4.

So, could I have cheated and just used the easy 2, 3, 4, 5 & 6 sequence at the top without bothering to do all the sums (though it wasn’t hard)?

Amused I.

Hence why I wanted to share it with you.
