89.

If you assign a number to each of the letters in the words of that sentence (A=1 up to Z=26) and add up the letters for each word, you get that sequence.

For example, What = 23 + 8 + 1 + 20 = 52
Is = 9 + 19 = 28.

So to get the last number we need to do the same for the word 'sequence': 19 + 5 + 17 + 21 + 5 + 14 + 3 + 5 = 89.
