Answer: After z the next value is aa, then ab and so on: a,b,c,d,e,f,g,h,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,aa,ab,ac,ad .... ax,ay,az,ba,bb,bc .... bx,by,bz,ca,cb,cc,cd .... As you can see it consists of two parts. The first letter goes up one (e.g. from a to b) and the last letter then goes all the steps from a to z, then the cycle is repeated (e.g. the first letter goes from b to c and the last goes all the steps from a to z).
