Answer 1

The mean of the data is x + 3.

Step-by-step explanation:

The set of values is,

S = {x, x + 1, x + 2, x + 3, x + 4, x + 5, x + 6}

The mean of a set of values is:

$\bar x=\frac{1}{n}\sum x$

Compute the mean as follows:

$\bar x=\frac{1}{7}[x+x + 1+x + 2+x + 3+x + 4+x + 5+x + 6]\\=\frac{1}{7}\times (7x+21)\\=x+3$

Thus, the mean of the data is x + 3.

Answer 2

1. mean= sum of all observations/no.of observations
2. so, when we add them we get
3. 7x+21/7
4. if we take 7 as common we get
5. 7(x+3)/7
6. 7 and 7will be cancelled we get
7. x+3=0
8. so x=-3
