The first 5 multiples of 5 are: 5, 10, 15, 20 and 25.5, 10, 15, 20, 25
-10
9 they are -20, -15, -10, -5, 0, 5, 10, 15, 20.
20, 15, 10, 5, 0, -5, -10, -15, -20 and so on.
mean = total_of_data_items ÷ number_of_data_items → total_of_data_items = mean x number_of_data_items → total_of_data_items = 4 x 5 = 20 So any 5 numbers that total to 20 will have a mean of 4. examples: {1, 3, 4, 5, 7}, {2, 3, 4, 5, 6}, {1, 2, 3, 4, 10}. {1, 1, 1, 1, 16}, {-15, -10, 10, 15, 20}
22.5
The first four multiples of five: 5, 10, 15, 20
The two numbers are 5 and 15. 5 + 15 = 20. 15 - 5 = 10.
5 and 10 10 and 15 15 and 20
5, 10, 15, 20, 25, etc.
5=2.236067978 10=3.16227766 15=3.872983346 20=4.472135955
Multiples. The numbers 10, 15 and 20 are multiples of 5.
