Find the missing number in the sequence: 10, 25, 49, 60, 75, 80. Assume one number is incorrect and needs replacement.

To find the missing number in the sequence $10, 25, 49, 60, 75, 80$, we need to identify the pattern. Since there is no explicit blank space, we assume one of the numbers in the given sequence is incorrect and needs to be replaced by the correct number that fits the pattern.

Step 1: Analyze the given sequence and look for common mathematical properties.
The sequence is $10, 25, 49, 60, 75, 80$.
Notice that $25 = 5^2$ and $49 = 7
