Fill in the blank so that the given statement is true.

The median is 77

65,68,78,82,89,__

To find the missing number that completes the sequence and makes the median 77, we need to arrange the given numbers in ascending order:

65, 68, 78, 82, 89

Now, we can see that the number in the middle is 78. Since the median is the value that separates the higher half from the lower half of the sequence, we need to replace 78 with 77 in order to achieve a median of 77.

Thus, the missing number is 77.
