Find the WRONG term in the given series. 12, 34, 100, 298, 894, 2674
894
The rule is "multiply by 3 and then subtract 2" at each step: \(\text{next} = 3 \times \text{current} - 2\).
Check from the start: \(12 \times 3 - 2 = 34\); \(34 \times 3 - 2 = 100\); \(100 \times 3 - 2 = 298\). These all hold.
Next should be \(298 \times 3 - 2 = 892\), but the series shows 894, which breaks the rule.
Confirm the tail: from the correct 892, \(892 \times 3 - 2 = 2674\) matches the final term, so only 894 is out of place.
Hence, the wrong term is 894.
