Oh, dude, you just add them up and divide by how many numbers there are. So, like, 51 + 52 + 56 = 159, and since there are three numbers, you divide 159 by 3 and get 53. So, the average is 53.
you minus the largest number by the smallest. So 56-48=8. The answer is 8.
It is 52, the middle number when they are in order.
the average age is 40
52, 54, 55, 56, 57, 58
52, 54, and 56. I would include 58, but the word 'between' means that it can not include the numbers on the ends (51 and 58).
when you put the numbers in order as described the number in the middle is the median. If 2 numbers are in the middle as in this case 56 and 58 you average them and get 57 as the median
51 + 56 = 107
50. 51. 52. 53. 54. 55. That is 6 numbers.
52, 54, 56, 58, 60, 62, 64, 66, 68, and 70 are.
56 * 52 = 2912
49, 50, 51, 52, 54 and 55 are the composite numbers between 48 and 56.
