There are infinitely many triplets.5 + 5 + 5
5 + 4.9 + 5.1
5 + 4.8 + 5.2 and so on.
And then, consider triplets where the second and third numbers have two digits after the decimal point:
5 + 4.99 + 5.01
5 + 4.98 + 5.02 and so on.
Next move to triplets where the second and third numbers have three digits, four digits, ... infinitely many digits after the decimal point.
All along, the first number has been 5. Replace it with 5.1 and go through the whole process again. And so on.

Mode is the average. You have to add all the numbers together, and then divide by how many numbers there are. Example: Add: 1+2+3+3+6= 15 then Divide: 15/5=3. Three is your mode.
The numbers are: -5 and 3

There is no answer to this. The factors of 15 are 1, 3, 5 and 15. The only numbers that add up to four are 1+3, 4+0 and 2+2.

The numbers are: -5 and 3
5 + 8 + 2 = 15. 15 / 3 = 5 All you have to do is add the numbers, then divide the answer by how many numbers you added.

Add up all the numbers and divide that total by the number of numbers. 1+ 2 + 3 + 4 + 5 = 15 15/5 = 3 The average is 3
