what is after quadruple

After quadruple comes quintuple, which means five-fold. Following quintuple, the next numbers in the sequence are sextuple (six-fold), septuple (seven-fold), octuple (eight-fold), nonuple (nine-fold), and decuple (ten-fold) . Beyond ten, the sequence continues with undecuple (eleven-fold), duodecuple (twelve-fold), tredecuple (thirteen-fold), and so on. These words are formed by taking the Latin root word for the specific number and adding "-ple" on the end, except for "double," which should be "douple," but the "p" becomes a "b" due to the voiced consonant "d".
