To evaluate the series, we must add up the values of the expression 5n as n goes from 3 to 8.
When n = 3, 5n = 5*3 = 15
When n = 4, 5n = 5*4 = 20
When n = 5, 5n = 5*5 = 25
When n = 6, 5n = 5*6 = 30
When n = 7, 5n = 5*7 = 35
When n = 8, 5n = 5*8 = 40
Adding these together, we get 15 + 20 + 25 + 30 + 35 + 40 = 165
Therefore, the value of the series is 165.
