it depends on how well the application is written, how broad the claims are, how strong the prior art is, how reasonable the examiner is, time of the year.... it is very common to have more than 3 office actions in one application. I' ve seen many with more than that.
Typically you will have a final OA coming in about six months. After that, if you want to continue the application, you would have to file RCE with new application fees. A final OA does not mean the application is dead but you do have to pay application fees to continue it.
