no. 
If you mean only two different toppings then you have 10 combinations. 5*4/2 because pepperoni and tomato is the same as tomato and pepperoni 
but with three toppings you have 
5 * 4 * 3 /6 choices 
and with 4 toppings you have 
5 * 4 * 3 * 2 / 24 choices (5 choices since you can leave off one of 5 toppings) 
and with 5 toppings you have 1 choice
