82-2=80 (third number) 80-6=74 (fifth number) 74-10=64 (answer) formula=ans-(x-4) Answer = 64
To find the fifth number, you can use the formula for finding the average of a set of numbers. The sum of the 5 numbers is 82 * 5 = 410. The sum of the 4 known numbers is 80 * 4 = 320. Therefore, the fifth number can be found by subtracting the sum of the 4 known numbers from the sum of all 5 numbers: 410 - 320 = 90. So, the fifth number is 90.
Two fifths (2/5, 0.4, or 40%) of 200 is eighty (80).
