The correct underlying pattern for this series involves subtracting consecutive odd numbers starting from 15. According to this rule, subtracting 15 from 196 should yield the next term, which would be 181. Following this, subtracting 17 from 181 gives 164, subtracting 19 from 164 gives 145, subtracting 21 from 145 gives 124, subtracting 23 from 124 gives 101, and subtracting 25 from 101 gives 76. The sequence perfectly matches this logic if the first term is 181, meaning the initial number 196 is incorrect.
