One is single, two is double, three is triple, four is quadruple, five 
is quintuple, six is sextuple. What are seven, eight, nine, and ten?

Hi, Vincent.

These forms parallel the (Latin) prefixes used for large numbers; see 
our archive entry, Names for Big Numbers, at:

The answers are: septuple, octuple, nonuple, decuple.

You gave me the answer about single, double, triple, etc. for seven, 
eight, nine, and ten. Can you give me eleven through twenty?

Hi, Vincent.

As for the high-number n-tuples, even those I gave you are not used 
often; You might just take my suggestion and look at the standard 
Latin prefixes, invent what you think the words ought to be, and then 
check a (big) dictionary to see if they are considered real. That's 
all I did to answer your first question!
