Correct Answer: 50
Solution :
Given:
2 : 10 :: 26 : ?
Here, add 1 to the square of consecutive odd numbers.
Like, (1)
2
+ 1 = 1 + 1 = 2
(3)
2
+ 1 = 9 + 1 = 10
Numbers 1 and 3 are consecutive odd numbers and the next odd number is 5.
Similarly, (5)
2
+ 1 = 25 + 1 = 26
(7)
2
+ 1 = 49 + 1 = 50
So, 26 is related to 50. Hence, the first option is correct.
