Given the following sequence of integers, can you identify the pattern in the sequence and how it should continue: 3, 3, 5, 4, 4, 3, 5, 5, 4, 3, 6, 6, 8, 8? Each value ( Vn ) in the sequence represents the number of letters in the English name of the corresponding numeral, beginning with the number one (without spaces and hyphens): one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, and so on. Here's the first part of the sequence with a few additional numbers: 3, 3, 5, 4, 4, 3, 5, 5, 4, 3, 6, 6, 8, 8, 7, 7, 9, 8, 8, 6, 9, 9, 11, 10, 10, 9, 11, 11, 10… Thanks again to Erik Veerman of Solid Quality Learning for this puzzle.
