Show answer & explanation

Correct answer: C

The series follows an alternating multiplication pattern: ×4, ×3.

3 × 4 = 12, 12 × 3 = 36, 36 × 4 = 144, 144 × 3 = 432.

The next term should be 432 × 4 = 1728, but the series shows 1738.

Verification: 1728 × 3 = 5184, which matches the final term.

Therefore, 1738 is the wrong term.
