Question

131 517 ? 123 what does the question mark represent

Answer 1

Answer:

192

Step-by-step explanation:

Because if you look closer the sequence as 2 digit instead of 3 digits the sequence will look like as below:13,15,17,q9,21,23,25....so on.

When we see 3 digits the sequence will be as below :131,517,192,123,252...so on
