Multiple choice

How do you represent the pythagorean triplets? Hint: If n1, n2 and n3 are pythagorean triplets, then n12 + n22 = n32.

  1. n-1, n, n+1

  2. 2n-1, n, 2n+1

  3. n, n2-1, n2+1

  4. n2-1, 2n, n2+1

  5. There are no such type of numbers.

D Correct answer
Explanation

Yes, this is the correct representation of the pythagorean triplets.

You can cross check substituting values (n2 - 1)2 + (2n)2 = (n2 + 1)2 Ex: 3, 4 and 5   (22 - 1)2 + (2x2)2 = (22 + 1)2 8, 15 and 17     (42 - 1)2 + (2x4)2 = (42 + 1)2
