Its very simple..

Use this formula, Wave number = R [(1/n1"2) - (1/n2"2)] *

772

Here, nl is the orbit corresponding to the series. In case

of our question, Balmer series corresponds to 2.

n2 is any other higher orbit. In the present case, the

limiting line is from infinity (ee).

As the atom is a hydrogen atom, Z=1.

R is the Rydberg Constant, R=109677 cm-1.

Now substitute all the values and you will get an

approximate answer as, 27419 cm-1.
