This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

The no should be of the form 1001n+1=x^2OR 1001n=(x-1)(x+1) since x sqr is 6 digit x is 3digits thus we keep x minus one or x plus one =multiples of143(a multiple of 1001) and tk the sol Keep the multiple s repeatedly intil 6digit sqr comes
