You can put this solution on YOUR website! Hi there, what the questions is asking you to do is sub values less then 11 into the equation to prove it gives a value less then 38..
x = 0, 3(0) + 5 = 5
x = 1, 3(1) + 5 = 8
x = 2, 3(2) + 5 = 11
x = 3, 3(3) + 5 = 14
x = 4, 3(4) + 5 = 17
x = 5, 3(5) + 5 = 20
x = 6, 3(6) + 5 = 23
x = 7, 3(7) + 5 = 26
x = 8, 3(8) + 5 = 29
x = 9, 3(9) + 5 = 32
x = 10, 3(10) + 5 = 35
x = 11, 3(11) + 5 = 38
not sure if needed, but you should see as you use any number in the sequence the next value given will be increased by 3.
hope this helps
