The answer is 5. 
You add all the numbers together then divide by the amount of number there are.
4+2+2+2+5+15=30 
30/6=5

The mean is found by dividing the sum of all terms by the number of terms present in the set.

Set up the equation:

\frac{2 + 2 + 2 + 4 +5 + 15}{6} = \frac{30}{6} = 5

The mean of this sequence is 5.

Pls, can someone answer this, Explain, using words and numbers, how to subtract 7x - ( 6x + 13). Remember to include the solutio
Hitman42 [59]
So first you distribute the negative to the 6x and 13 which will flip the sign of both of them to -6x and -13 so take away the parentheses and the equation is now 7x-6x-13. You combine the x’s and you get 1x-13 or x-13
