$\text{Average}=\frac{\text{Sum of values}}{\text{Number of values}}$

Given values: $2𝑥$, $6𝑥$, $8𝑥$, $10𝑥$, $12𝑥7$

Sum of values: $2𝑥+6𝑥+8𝑥+10𝑥+12𝑥7=2𝑥+6𝑥+8𝑥+10𝑥+84𝑥=110𝑥$

Number of values: 5

Now, divide the sum by the number of values:

$\text{Average}=\frac{110𝑥}{5}=22𝑥$

So, the average of $2𝑥$, $6𝑥$, $8𝑥$, $10𝑥$, and $12𝑥7$ is $22𝑥$.
