Answer 4

The consecutive even numbers: \[x,x+2,x+4,x+6,x+8,x+10\]
the average:
\[\langle x\rangle=\frac{x+(x+2)+(x+4)+(x+6)+(x+8)+(x+10)}{6}=13\]

Answer 5

\[\frac{6x+30}{6}=13\]

Answer 6

Thanks! XD

Answer 7

\[x+5=13\]

Answer 8

8 XD

Answer 9

\[\frac{(8+10+12+14+16+18)}{6}=\frac{78}{6}=13\]
