It is 56, the middle number.
The numbers, in size order, are 56, 64 and 88. The middle number now is the median and that is 64.
64, because it is the middle value when the numbers are listed in numerical order.
The multiples of 8 between 30 and 90 are: 32, 40, 48, 56, 64, 72, 80, and 88.
184. The difference between each term is -2 times the previous difference: 100 + -4 = 96 96 + (-4 x -2 = 96 + 8 = 104 104 + (8 x -2) = 104 + -16 = 88 88 + (-16 x -2) = 88 + 32 = 120 120 + (32 x -2) = 120 + -64 = 56 So the next difference is -64 x -2 = 128: 56 + (-64 x -2) = 56 + 128 = 184

8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88.
They are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, and 96.
mean = (65 + 56 + 57 + 75 + 76 + 66 + 64)/7 = 65.57 median = "middle" number = 65 mode = most common number = all are equally common
184. The difference between each term is -2 times the previous difference: 100 + -4 = 96 96 + (-4 x -2 = 96 + 8 = 104 104 + (8 x -2) = 104 + -16 = 88 88 + (-16 x -2) = 88 + 32 = 120 120 + (32 x -2) = 120 + -64 = 56 So the next difference is -64 x -2 = 128: 56 + (-64 x -2) = 56 + 128 = 184
64% of 88 = 88*64/100 = 56.32
The median is 84.

184 * 100 to 96, subtract 4 * 96 to 104, add 8 * 104 to 88, subtract 16 * 88 to 120, add 32 * 120 to 56, subtract 64 * 56 to 184, add 128 See the pattern here? you alternate subtraction and addition in between each two numbers and double the value to add or subtract each time.
