Solving a H Atom Energy Problem: Am I Being an Idiot?

In summary, the conversation is about finding the minimum energy photon that an H atom in its ground state can absorb. The formula being used is En2-En1=hcR∞(1/n12 - 1/n22), but there is confusion about the values for n1 and n2. The correct ground state is n = 1, not n = 0, and the final term should be 1/4. The conversation ends with a playful remark about the "solved" button.

I am having a problem with this question in a past exam paper...I may just be being a bit of an idiot:

Show that if an H atom is in its ground state the minimum energy photon it can
absorb is 1.634x10-18 J.

I am using The formula:

En2-En1=hcR∞(1/n12 - 1/n22)

I keep getting a different value using n1 as 0 and n2 as 1...also using 1 and 2 respectively.
What am I doing incorrectly?

The ground state is n = 1 (not n = 0).

Sorry...I was forgetting to do 1/4 for the final term...It has been a long day.
