So to get the mean, you need to work out the sum of the values and divide it by the number of values there are.
This means you should do:
(Let x represent the fifth score)
(92 + 85 + 90 + 92 + x) / 5 = 90
(92 + 85 + 90 + 92 + x) = 450
359 + x = 450
x = 450 - 359
x = 91
So the answer is 91 and you are correct :)
