Explanation

Pattern: 169 (+15) = 184; 184 (-45) = 139; 139 (+75) = 214 (not 216); 214 (-105) = 109; 109 (+135) = 244. The pattern is +15, -45, +75, -105, +135. 216 is the wrong number.

AI explanation

The series follows an alternating pattern where the differences are 184 - 169 = 15, then subtracting 45 for the next step, adding 75, subtracting 105, and adding 135. Starting from 169, adding 15 gives 184, subtracting 45 gives 139, adding 75 gives 214, subtracting 105 gives 109, and adding 135 gives 244. Therefore, the number 216 is the wrong term in the sequence.
