Tick (✓) the correct answer
Which of the following is a pythagorean triplet?
(a) (2, 3, 5)
(b) (5, 7, 9)
(c) (6, 9, 11)
(d) (8, 15, 17)
Solution:
(d) (8,15,17)
This can be understood from the property of Pythagorean triplets. According to this property, for a natural number $m,\left(2 m, m^{2}-1, m^{2}+1\right)$ is a Pythagorean triplet.
Here, m = 4
2m = 8
m2 - 1=15
and m2 + 1 = 17
