77798.

In the other five numbers the second pair of digits is 1 higher than the first pair of digits, eg 89+1=90, whereas the jump is 2 in 77798.

I'm assuming the last digit is a red herring, but this may be more complicated than it first appears!

It's the first digit of the next number in line.

All the other numbers can be read as follows:
89 90 9(1)
69 70 7(1)
28 29 3(0), etc.
