Explanation

This series appears to follow the pattern: multiply by position, add something, or similar. Checking: 13×2+8=34, 34×3+26=128, 128×4+68=580, 580×5+185=3025. The pattern seems complex and 128 doesn't fit simpler patterns. Given the options, 128 is marked as wrong, possibly because it breaks a simpler expected pattern like doubling with additions.
