Another Puzzle
Trey Klein sent me another puzzle…
“Find the missing 13th number in this sequence:
77, 341, 923, 1547, 608, 2116, 377, 2263, 518, 1394, 3182, 1645, _____ , 944, 4636, …”
Anyone who solves this, I’d like you to post the sequence of tactics and ideas by which you solved it, in the comments. (Yes, I have solved it, and I’ll put my method in a comment, too.)
COMMENTS WILL CONTAIN SPOILERS, so don’t look unless you want the secret. Trey offered some hints, but I’m against hints, so I won’t publish them.
