OOPS

That is what I get for trying to do anything that takes any thought at that time of the morning. Fixed errors in the post, check it again. Sorry ;-)

Re: Tuesday Puzzle

All three numbers share a common digit.

The second and third have two digits in common.

I don't know the answer but once it is posted I'll be off to the gas station to buy some lottery tickets.

One answer

is 61 (127) 71

But I suspect that is not what you had in mind, since it doesn't depend on any relationship between the columns. I just continued the second differences of 4 in the outside columns and negative 8 in the inside column.

Correct. The actual numbers are in Alex's post below. Another way of seeing the pattern involves 2,3,4,5,6,7,8,9,10 and 1,2,3,4,5. Can you see it?

Re: ;-)

Yes, the pattern I observed was:

Non-parenthesized numbers increase by successive numbers starting with 2. e.g 17 + 2 = 19, 19 + 3 = 22, etc.

Parenthesized numbers are the sum of the non-parenthesized numbers in the row, minus the row number. e.g. 61 + 71 - 5 = 127.
