Average= (36+49+64+81+100)/5 =330/5 =66
81.25 is the average of those numbers.
They are: 83, 89 and 97
36, 49, 64, 81, 100
It depends on what average you want to find. To find the mean of 81, 81, 98, and 91 add the numbers together and divide by 4 (the number of numbers you added). 81 + 81 + 98 + 91 = 351 351 divided by 4 = 87.75. To find the median, list the numbers in order and find the one in the middle. 81, 81, 91, 98 81 and 91 are in the middle. To find the mode, look for the number that appears the most, 81 appears twice and the other numbers appear once. 81 is the mode.
