1. It first threw me that the first 4 numbers were 18 apart…

2. Same, then the 61 and 115 are 54 apart (18×3)

3. I liked this brain game. I got 124 though.
   1+2+4=7

4. I’m with Kate, I didn’t think to look for an odd number

5. I agree with Chris. I got 169.

6. Ah! That explains why each interval is a multiple of 9…

7. Why is it called “Well Do Ya?”

8. Since the first intervals were 18 and the last is 54 (3x 18)m I thought the next number would be 169.

9. I love almost *seeing* people think by reading these comments. Too many of my number sequences had been based on text and ordinal numbers, so I figured something with a little math was in order.

   This puzzle would have been far too easy without the “odd number” proviso.

10. Good question, Mike. If no one else answers in a while, I’ll tell ya.

11. Lucky number seven.
    Ask yourself one question. “Do I feel Lucky?”

12. Bingo, Duggy. Exactly right.

13. noticed that they all added up to 7, and that it skipped one every time (7, no 16, 25, no 34, 43, etc.), so figured it out that way. Failed to notice that the ones it skipped were even #s…

    though now that I look at it again, it skips 70 and 106, so that pattern doesnt hold true. oh well close enough i suppose

15. Yessssssss. I got this one.

16. I got 124.
    1+2+4 = 7.

17. I like when the numbers follow an obvious pattern until the one that forces a rethink. The 115 was the first one I noticed added to seven, and from there, the pattern fell into place for me.

18. got the same result by a “slightly” more round-about method..
    7 = 6×1 +1 -> 1
    24 = 6×4 +1 -> 4
    43 = 6×7 +1 -> 7
    61 = 6×10 +1 -> 10
    115 = 6×19 +1 -> 19
    considering alternate numbers in the rightmost column..
    7-1 = 6
    19-7 = 12
    ..
    10-4 = 6
    ? – 10 = 12 => ?=22
    6×22 +1 = 133
    wheeeeee…

19. I found another sequence:

    start with 7 = 7
    add 18 = 25
    double and subtract 7 = 43
    add 18 = 61
    double and subtract 7 = 115
    add 18 = 133
