Dr. Pepper-
What’s next:
“I think the pattern starts earlier, 1,4,9,61,52,63,94,46,18,001,121,441,961,691,522…”
Correct!
Whole numbers starting from 4 are squared, then the resulting number has its digits reversed.
(you could’ve said “…9,4,1,0,1,4,9,61,52,63,94,46,18…” if you REALLY wanted earlier)
Are you a math teacher?
If so, were my results for Squeak’s puzzle correct? What approach would you have taken?
