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

-- To average 70 on four tests, the total of the scores has to be 280 .-- You already have (64 + 69 + 73) = 206 on the first three tests.-- You need (280 - 206) = 74 on the fourth one in order to average 70 on all four.You can do it !Is that kind of what you were asking ?

"Should" is subjective. It depends on the type of loan you are attempting to get. FHA loans accept lower credit scores than traditional lenders. Traditional lenders have rate discounts at the higher levels, the best loans being found with scores over 800. Each lender is different. Some price everyone the same over 750, or 720. On average a score over 680 is desirable, although loans can be had with lower scores. Don't forget that lenders are now placing a greater weight on debt ratios and down payment levels.
