a(1) says: there will be one 2 in a(2). a(2)=2 because a(1) said so; and a(2)=2 says: there will be two 3's in a(3). a(3)=33 because a(2) said so; and also a(3) says: there will be thirty three 4's in a(4). Therefore a(4)= 444444444444444444444444444444444 (33 times the digit 4). And a(5)= 555555555555555...555 (with 444444444444444444444444444444444 5's).
