Solve mean(1,2,3,4,5,6,7,8,9,10)

$$mean(1,2,3,4,5,6,7,8,9,10)$$

Evaluate

$$\frac{11}{2}=5.5$$

Solution Steps

To find the mean of the set 1,2,3,4,5,6,7,8,9,10 first add the members together.

$$1+2+3+4+5+6+7+8+9+10=55$$

The mean (average) of the set 1,2,3,4,5,6,7,8,9,10 is found by dividing the sum of its members by the number of the members, in this case 10.

$$\frac{55}{10}=\frac{11}{2}$$

Factor

$$\frac{11}{2} = 5\frac{1}{2} = 5.5$$
