It’s been a little while since my last post… I plead spring break vacation. At any rate, hopefully you figured out that the last post was intended as an April Fool’s joke. I hope you didn’t embarass yourself too badly trying to guess random numbers. (=

Here are some number sequences. Can you figure out the pattern and give the next three terms for each? (Each sequence follows a different pattern.)

note: square brackets indicate positions/subscripts.

1. 63, 127, 255. Pattern: [n+1] = 2n+1

2. 365, 1094, 3281. Pattern: [n+1] = 3n-1

3. 42, 56, 72. Pattern: [n+1] = n+([order in sequence of # n+1]*2)

4. Don’t want to try :-D

4. Add the digits together and double the result. So 8, 16, 14.
