Depends on what panel layout he has.
The EFIS style layout has the N2 under the N1 and EGT indicators, but the PFD/ND is a bit more trickier.
Here you have two options: either the compact MFD which shows the N2 on the upper MFD, or the Over/Under which has the N2 on the lower DU
I guess you have the Over/under layout so do this:
right click on the MFD, the lower DU will popup and it will be blank. Now press the "ENG" button above the MFD :)
