May not be a unique way, but I think he just wants the simplest or any way. Either way it stumps me.

Well, if he want any way, 7 will do fine!:rofl:

Try the sequence 14,23,28,34,42,? At least it has an answer (particularly for NYC residents).

um...
..., 96, 10000000000, 10000000000000

This is an old problem. Here's the answer

10, 9, 60, 90, 70, 66, 314, Kermit, 7, 2, 2, 19, 43, Wyoming, 14343, 22, 43, 44, 1.654342, the Larch, 22, 23, 24, 0, 5, ....

The pattern should now be obvious.
