Correct Answer: 225


Solution : Given:
34, 63, 94, 131, 172, 225

Add consecutive prime numbers starting from 29 to obtain the next number –
34 + 29 = 63; 63 + 31 = 94; 94 + 37 = 131; 131 + 41 = 172; 172 + 43 = 215
The required number is 215 instead of 225.

So, the wrong number in the series is 225. Hence, the fourth option is correct.
