Answer:
the fifth number is 11
Step-by-step explanation:
8,11,13 and 17, x
the mean is =12 ( which means the sum of the terms divided by the numbers of terms )
to find the mean :
(8+11+13+17+x)/5 =12
5*12=49+x
60-49=x
x=11
3x + 14 = 20 - 2x
add 2x to each side
5x +14 = 20
subtract 14 from each side
5x = 6
x = 6/5 = 1 1/5
Answer: 1 1/5
