Find the wrong term in the series given below. 31, 64, 194, 784, 3925, 23556

The series pattern is: multiply by 2 and add 2, then multiply by 3 and add 2, then multiply by 4 and add 2, etc. Checking: 31×2+2=64 (correct), 64×3+2=194 (should be 194), 194×4+2=778 (but given 784 - WRONG), 778×5+2=3892 (but given 3925), 3892×6+2=23374 (but given 23556). The error starts at 194. If we replace 194 with the correct value following the pattern, we can verify 194 is indeed the wrong term.
