Rajasthan Police Constable Model Paper 3

The pattern followed here is:
Second number is double the first number and third number is thrice the first number.
1) 108, 216, 314 → 108 × 2 = 216, 108 × 3 = 324 ≠ 314
2) 16, 32, 48 → 16 × 2 = 32, 16 × 3 = 48
3) 114, 228, 342 → 114 × 2 = 228, 114 × 3 = 342
4) 112, 224, 336 → 112 × 2 = 224, 112 × 3 = 336
Hence, answer is option 1.
