Ask AI: what is the next number in the sequence of 196,113,140,250,153,134,171?

The pattern appears to be composed of alternating calculations: subtraction first, then addition. The differences between the first and second numbers, and then the third and fourth, and fifth and sixth numbers are 83, 110, and 19, respectively. The pattern for these differences seems to be adding 27 each time (83+27=110, 110-91=19). If we continue this pattern, the next difference would be 19 - 72 = -53. Now if we apply this to the seventh number in the series (171), we subtract 53 from 171 and get 118 as the next number.
