1. 7, 9, 66, 12, 14, 66, 17, ... choose which pair of numbers comes next?
Solution:
This is an alternating addition series with repetition, in which a random number, 66, is interpolated as every third number. The regular series adds 2, then 3, then 2, and so on, with 66 repeated after each "add 2" step.
