2 tattoos on each arm is a total of 2*2=<<2*2=4>>4 tattoos.
3 tattoos on each leg is a total of 2*3=<<2*3=6>>6 tattoos.
Thus, Jason has 4+6=<<4+6=10>>10 tattoos.
Twice the number of tattoos that Jason has is 2*10=<<2*10=20>>20 tattoos.
Adam has 3 more than twice the number Jason has, or 3+20=<<3+20=23>>23 tattoos.
