I’ve been asked to solve this.



You can Google the answer, which is 4C6 --> 5E1 --> 7A7 --> 3C8 --> 5Y9 --> 3A1 --> 2H2 but HOW? I can’t just stick the answer down without knowing how. Any smart arses work it out?

I think the answer you've found on google is wrong, and the correct answer is 4C6, 5E1, 7A7, 3A1, 5Y9, 3C8, 2H2.


In each circle, subtract the 2nd number from the 1st. That number gives you the number of letters in the alphabet between the letter in this circle and the letter in the next circle. eg. 4C6; 6-4=2, C + 2 places =E, so the 2nd pattern will be the one with an E in it.

It passes the sniff test! Any advances on this?

I hate these questions. Mainly because I never get them, and partly because there must be an infinite number of answers. The real question is 'guess the arbitrary continuation of this sequence'.

Those numbers could relate to anything. Substitutions? Coordinates? Chapters in some obscure Welsh poem?

That only works for the first two circles. It doesn't get you from E to A

1-5 + E(5) gets to A
Now if they hadn’t drawn the line up the first A it would be tough.

Yes, and then what?

Seems reasonable!

Aye, must be 30+ years since I was at school and were told that if we didn't understand Pythagoras or the more difficult calculus, that would be us on the scrap-heap in terms of job opportunities.

Couldn't even have a calculator in exams - we were told that there is no chance you will ever be in a situation where you will have a pocket calculator to pull out in times of difficulty in the future so you may as well learn to use the tables;, sine, cosine etc.

30 years later, we aren't carrying a calculator but a piece of kit unfathomable at the time - phones now are essentially the Hitchhiker's Guide

Also, this person is correct.

How do you get from E to A? And then from A to Y?

It's not correct. At least, not without additional goalpost movements.

I don't have one, but that answer is demonstrably not correct.

Just because it's the only suggested solution doesn't make it right.

5E1

1-5 = -4, E+ -4 = A

There are then 2 with A in the middle. The 7A7 keeps you on A so use that one first, then the next A is 3A1, 1-3 = -2. A+ -2 = Y so 5Y9, 9-5 = 4. Y+4 = C, so 3C8, 8-3 = 5, C+5 = H.

Checks out for me.
