Question

Find the wrong number in the series 66,91,120,153,190,233,276

Answer 1

190 I think so it helped

Answer 2

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.
