The average of 12, 6 & 24 = (12+6+24)/3 = 42/3 = 14.
The average of 6, 15 and m is (6 + 15 + m) / 3 = (21 + m)/3 = 7 + m/3
15 plus -3 equals 12 12 divided by -6 equals -2
3, 6, 9, 12, 15
15: (15, 1) (5, 3) 12: (12, 1) (6, 2) (4, 3)
the greatest common factor of 6,12, and 15 is 3.
The GCF is 3.
The average of a sequence of numbers is equal to Average(x1, ... , xi) = Sum(n, i = 1)[xi]/n Example: Find the average of 5, 6, 8, 12, 15, and 29. Average = Sum[5, 6, 8, 12, 15, 29]/6 Average = (5+6+8+12+15+29)/6 Average = 11
9 and 6 9+6 = 15 9-6 = 3
The first 5 multiples of 3 are as follows: 3, 6, 9, 12, 15
The factors of 12 are 1, 2, 3, 4, 6, and 12 The factors of 15 are 1, 3, 5, and 15
Average of 4, 5 and 6 = (4+5+6)/3 = 15/3 = 5
