(Omit "and" in both.) %C A249030 Take the number of letters in the spelling of a number and subtract the number of syllables in the sounding of that number. For example, zero has four letters and two syllables generating 4-2=2 for the first term. As such it is linked to sequences A005589 and A075774. %F A249030 a(n) = A005589(n) - A075774(n). %Y A249030 Cf.
