Pythagoras triplet means set of three numbers which follow the Pythagoras theorem.

e.g , Let A = {a, b, c} is a Pythagoras triplet. When a² = b² + c², or b²=c²+a², or c² =b²+a² .

How to find triplet .

step1:- Let 2n= 8 , then,n = 4

step2:- largest number of triplet = 4n+1 . From above n =4 put it here,

Largest number of triplet = 4×4+1 = 17

step3:- middle number of triplet= 4n-1 .now put n = 4 , then,Middle number of triplet= 4×4-1 = 15

Hence, Pythagoras triplet is { 8, 15 , 17} .

You can check it .

8² +15² = 17² , follow Pythagoras theorem.

first we will find the square root of 4931

square root of 4931 = 70.221...

and then find the square of 71

square of 71 = 5041

then subtract 4931 from 5041

5041 - 4931 = 110

so, 110 will be added to 4931 to make it a perfect square.

Hope it helps you :)
