You can put this solution on YOUR website!
Say he caught +n+ fish the 1st day
2nd day: +n+%2B+4+
3rd day: +n+%2B+4+%2B+4+
4th day: +n+%2B+4+%2B+4+%2B+4+
etc.
------------------------
+200+=+10n+%2B+4%2A%28+1+%2B+2+%2B+3+%2B+4+%2B+5+%2B+6+%2B+7+%2B+8+%2B+9+%29+
+200+=+10n+%2B+4%2A45+
+200+=+10n+%2B+180+
+10n+=+20+
+n+=+2+
