Quick Number Puzzle

And given that that was the author’s intention, the fact that there is a second possible solution is simply an anomaly based on the random sequence they chose.

You think they happened to randomly pick a group of numbers that followed the sequence 18n+1?

There’s a difference between the palindrome solution and the mathematical solution.

Consider: 19 - 37 - 55 - 73 - 91 - What’s the next number in this sequence?

The palindrome spotters are going to say there is no next number; the sequence is complete. The mathematicans would say it’s an open-ended sequence and the next number is clearly 109.

Of course the solutions are different. But this palindrome spotter (with a BS in math) says you’ve now posed a different problem, and it’s obvious a palindrome is not the answer.

I did it Otto’s way.
