Example

a(1) = 999 added to 1 (the reshaped integer 1000 without its last two digits) is 1000;
a(2) = 1000 added to 1 (the reshaped integer 1001 without its last two digits) is 1001;
...
a(6517) = 380880 added to 381 [the reshaped integer a(6518) =  381261 without its last three digits] is indeed 381261 = a(6518).
