# Numerator...Denominator...Terminator!

Level pending

Consider the following sequence -

$\displaystyle \frac{1}{2}, \frac{5}{3}, \frac{11}{8}, \frac{27}{19} \cdots$

Now, if $${T}_{n}$$ is the nth term of this sequence and $$N({T}_{n})$$ is the numerator of the term and $$D({T}_{n})$$ is the denominator of the term, then find $\displaystyle \text{digit sum} \left (\dfrac{N({T}_{17}) + N({T}_{29}) - D({T}_{17}) - D({T}_{29})}{{(\displaystyle \lim_{n \rightarrow \infty}({T}_{n}))}^{2}} \right)$
