An average is worked out by dividing the total of the scores by the number of scores. You have 4 scores already so when you have done the next test it will be 5 scores. If you multiply 5 scores by 90 it gives you a total score of 450. The 4 scores you already have adds up to a total of 354. If you subtract 354 from the 450 you get 96 and that is your target for the final test. The average for the first 4 tests comes out at 88.5
