%N Values of self-describing sequence A154328 at jumps, a(n) = A154328(A154329(n)) > A154328(A154329(n)-1)+1.

%C See A154328 and A154329.

%e a(1)=10 since at the first jump of A154328, which occurs at index i=2, the value raises to A154328[2]=10 > A154328[1]+1=2.

%e a(2)=20 since at the 2nd jump of A154328, which occurs at index i=5, the value raises to A154328[5]=20 > A154328[4]+1=13.

%e a(23)=10^31-10^12 since at the 23rd jump of A154328, which occurs at index i=498, the value raises from A154328[497]=10^30-1 to A154328[498]=10^31-10^12.
