Ive been working on that one -how did you come by those figures- :lol: RDY-B

It seemed to me to be the only suitable pattern left over. But I couldn't create a proof to confirm it. So it's not certain.

None of the lines are consecutive 1,2,3,4, ....

It is not grouped as odds and evens

None of them appear to have a + - x / sequence or similar total.

They didn't fit as Fibonacci numbers

The clue meant that 5 was in the sequence.

However 5 cannot be the last digit, unless you 1,2,3,4,5 which is a direct sequence. Eliminated in step one.

The line below contains 1,2,4, Since the pattern show no duplicates in a three digit combo going down. I went with what would be next. 1,3,4

The next number would have to be 5 to complete the clue.

4,5,6 was also in the line below so 7 seemed appropriate.

1,3,4,5,7

It's not a proof. It's a bad guess. But I figured what the heck.

Sincerely,

Brendhan
