what is the value of Rydberg's constant-109677/cm or -2.18*10raised to the power-18

Q. Find the wavelength of the first line of spectral series of $H{e}^{+}$ ion whose interval between extreme lines is $\frac{1}{{\lambda }_1}-\frac{1}{{\lambda }_2}=27419.25{\text{cm}}^{-1}$
(Take Rydberg's constant $R=109677{\text{cm}}^{-1},\frac{1}{109677}=9.11\times {10}^{-6}cm$)
