Choices:-
(3,4,5)
(5, 12, 13)
(8,15,18)
(7, 24, 25)​

Answer 1

Answer:

option c is the correct answer

Answer 2

Answer: The odd one is (8, 15, 18) .

Step-by-step explanation:

Firstly we will establish connection among the numbers in given pattern.

(3,4,5)

Here in this pattern the largest number is 5 and the other two numbers are 3 and 4. Sum of squares of 3 and 4 is equal to the square of 5.

5² = 3²+ 4²

⇒ 25= 9+16 = 25

(5,12,13)

Here in this pattern the largest number is 13 and the other two numbers are 12 and 5. Sum of squares of 12 and 5 is equal to the square of 13.

⇒ 13² = 12² +5²

⇒169 = 144 + 25 =169

(7, 24, 25)

​Here in this pattern the largest number is 25 and the other two numbers are 24 and 7. Sum of squares of 24 and 7 is  equal to the square of 25.

⇒ 25² =24²+ 7²

⇒ 625 = 576 + 49

⇒ 625 = 625.

(8,15,18)

Here in this pattern the largest number is 18 and the other two numbers are 15 and 8. Sum of squares of 15 and 8 is not equal to the square of 18.

⇒ 18²≠ 8²+15²

⇒ 324 ≠ 64 + 225

⇒324 ≠ 289

The odd one is (8, 15, 18) which is not following the established pattern.

Hence,  the odd one is (8, 15, 18) .
