Given that \(l_{19} = 100000 \) and that \(q_x=0.000034x^2\). calculate \(l_{17}\).

I tried to use \(_{2}p_{17}\) but i got stuck where i had to compute \( \frac{l_{19}}{(1-_2q_{17})}\) because i already had a value of \(q_{17}\) not \(_2q_{17}\). it would be wrong for me to multiply \(q_{17}\) by 2 right?
