Notice that we can separate this into two sequences: and . Our complete solution set in the given range is and . It's easy to see that is the 201st term and 994 is the 200th term, so there are total solutions in the given range.
On lihtne näha, et on 201. perspektiivis ja 994 on 200. perspektiivis, mistõttu on täislahendusi antud vahemikus.
