The energy required to excite an electron from n=2 to n=4 state in a hydrogen atom can be calculated by adding the given energy values.

The given energy values are -0.85 eV, 4.25 eV, -3.4 eV, and 2.55 eV.

Step 1: Add the energy values

-0.85 eV + 4.25 eV - 3.4 eV + 2.55 eV = 2.55 eV

So, the energy required to excite an electron from n=2 to n=4 state in a hydrogen atom is 2.55 eV.
