For example: If I start with 11... Double 11 is 22 Subtract 1 is 21 Reverse the digits is 12 ...which is close, but not correct. |
1, if single digits are allowed. |
Otherwise it's 37. |
Correct, 1 and 37 both work. Now, anyone for an answer over 100? |
Am I the only one playing? Looks like it - 397. |
Yup. And then the next one after that? (There is a pattern, honest) |
3997? |
Then 39997? |
Yup. Yup. Anyone care to give us infinitely many answers? |
Nope. Fed up now. |
