Problem of the day for Wednesday, May 16

If

then what is N?


  • OK, what are we going to do this time? Algebra, anyone?
  • First, let's figure out what the left side equals. Since 2 + 3 + 4 = 9, and 9/3=3, so the left side is equal to 3.
  • That means that N should be 1/3 of 2002 + 2003 + 2004, so that the fraction on the right will equal 3.
  • Since 2002 + 2003 + 2004 = 6009, we get that N = 2003.
  • There's a pattern here!
