Well, depends on what story you are reading... Maybe I can help you you give me the title of the novel. ^w^
The answer is; riding without one is dangerous and reckless.
4L because 200 x 20 = 4000mL
and 1000 mL is 1L so 4000mL is 4L
gl!
Let, the integers = x, x+2, x+4
It is given that, x + x+2 + x+4 = 156
3x + 6 = 156
3x = 156 - 6
x = 150/3
x = 50
So, x+2 = 52; x+4 = 54
In short, Your Three Integers would be 50, 52 & 54
Hope this helps!
