Average(5, 10, 15) = (5 + 10 + 15)/3 = 30/3 = 10
5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15
5
Well, honey, if you wanna find the number smack dab in the middle of -5 and 15, you just average those two bad boys. So, (-5 + 15) / 2 = 5. There you have it, sweet cheeks, 5 is the magic number that's halfway between those two extremes.
5 10 15 10 5
-5 It is 15 more than -20 and 15 less than 10 To find a halfway point (which is also the average), add the numbers together and divide by 2. -20 + 10 = -10 and -10/2 = -5
If the average is 10 then 15 is 5 above average.

It means you are counting in increments of 5. 5+5=10, 10+5=15. If by the word "mean", you are talking about the average, then the mean is 10. To determine the average of any group of numbers, add the numbers and divide the total by the number of numbers added - (does this makes sense?) Example: 5 + 10 + 15 = 30. Divide 30 by 3 (you added 3 numbers together to get the total) and the average is 10. Hope this helps.
15. 5 - -10 = 5 + 10 = 15 → 15 + -10 = 15 - 10 = 5
5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15
7+7+7+14+15=50 50/5=10 Your answer is 10.

To achieve a mean of 10 with four numbers, their total must be 40. If the median is also 10, then when the numbers are arranged in order, the average of the two middle numbers must equal 10. This can be done with combinations of numbers such as 5, 5, 15, and 15, which satisfy both conditions: their mean is 10, their median is 10, and none of the numbers are 10.

Three pairs of numbers with a GCF of 5 are: 5 and 10, 10 and 15, and 5 and 15.
