Question

find the average of first 6 multiples of 3

Answer 1

Mode: You just want to add them all up (3, 6, 9, 12, 15, and 18 as they are the first 6 multiples of 3), and then divide by six as there are six numbers, so 3 + 6 + 9 + 12 + 15 + 18 = 63. 63 divided by 6 is 10.5

Answer 2

First six multiples of 3 are
3 6 9 12 15 & 18.
Mean = 3 + 6 + 9 + 12 + 15 + 18 / 6
= 63 / 6
= 10.5
