Answer:
The wrong number in the provided series is 233.
Step-by-step explanation:
Consider the provided number in series and observe the pattern as shown.
91 - 66 = 25
120 - 91 = 29 which is 25 + 4
153 - 120 = 33 which is 29 + 4
190 - 153 = 37 which is 33 + 4
233 - 190 = 43 which is not equal to 37 + 4
276 - 233=43
Here, we can observe that the difference of each number is 4 more than the previous difference, except the 6th term which is 233.
The 6th term should be 190 + 37 + 4 = 231.
Therefore, the wrong number in the provided series is 233.
