To determine the next number in the pattern, we need to identify the rule or pattern that generates the given sequence. Looking at the differences between consecutive terms, we can see that the sequence is decreasing by 49, then 36, then 25, then 16, and then 9.
Therefore, the next number in the sequence should be 41 - 4^2 = 25.
So the missing number in the pattern is 25.
Hence, the complete pattern is:
167, 118, 82, 57, 41, 25.
