i live in a single family attached home, its a condo. i was hoping to put up a 100 lb punching bag in the garage, but i cant seem to find a stud. ive drilled numerous holes trying to find one, and i think i finally did.

does anyone know how far apart the studs are from each other??
it seemed like the stud was about 5-6 inches from the drywall, is that right?

any help is much appreciated.
