The correct answer is 154.

Fibonacci Series: Each term is the sum of the two preceding terms. Series based on specific rules: Patterns involving squares, cubes, prime numbers, etc., or complex rules like the one found in this problem ($(T_{n-1} \times k) \pm c$ or $(T_{n-1} \times n) \pm c$). Solving these problems often requires trial and error, testing different potential patterns based on how the numbers change from one term to the next.
