Note that 1 has two syllables (u-no) but 1 is not in the sequence because 1 < 2.

EXAMPLE
a(1) = 2 since "dos" is the least number to have only one syllable.
a(2) = 4 because "cuatro" is the first number > 2 to have two syllables: cua-tro.
a(3) = 14 because "catorce" is the first number > 4 to have three syllables: ca-tor-ce.
a(4) = 17 because "diecisiete" is the first number > 14 to have four syllables: die-ci-sie-te.
a(5) = 31 because "treinta y uno" is the first number > 17 to have five syllables: trein-ta-y-u-no.
