In trying to understand what you mean, you presented a sequence of four terms and you refer to "series", so you must want the sum of those terms. While I have forgotten the formula to use, I know that the series will be 18+32+50+72, or
(18+72) + (32+50), in any way the sum is 172.

18 14 4 0 -94
32 18 4 -94 -94
50 22 -90 -188
72 -68 -278
4 -346
-342
The sixth term could be -342
