Show answer & explanation
Correct answer: C
The given series follows the pattern n^3 + n.
Checking the options against this pattern:
- 738: 9^3 + 9 = 729 + 9 = 738 (Valid)
- 349: Does not satisfy n^3 + n for any integer n.
- 520: 8^3 + 8 = 512 + 8 = 520 (Valid)
- 222: 6^3 + 6 = 216 + 6 = 222 (Valid)
Therefore, options A, C, and D are correct.
