Number is n
Three times the sum of a number and 4.
= 3* ( n + 4) = 18
3n + 12 = 18.
3n = 18 - 12.
3n = 6
n = 6 / 3.
n = 2.

Answer:
Mean: 8
Median: 8
Mode: 8
Step-by-step explanation:
Find the average
Mean: 3 + 4 + 5 + 7 + 8 + 8 + 9 + 13 + 15 = 72
Divide by the amount on numbers: 72 / 9 = 8
8 is the average
Find the middle
Median: 3, 4, 5, 7, 8, 8, 9, 13, 15
8 is the middle
Find the most common
Mode: 3, 4, 5, 7, 8, 8, 9, 13, 15
8 is most common
