Consider set 1 as 1,4,9 and set 2 as 2,8,18. When these sets are combined, the median would be 4+8/2 which is 6 which is an integer. In this case, the range is 18-1 which is 17. Therefore shouldn't F also be considered as an option?
Consecutive numbers are numbers that follow each other in order. They have a difference of 1 between every two numbers.
i.e. n, (n+1), (n+2), .....
Consecutive even numbers are even numbers that follow each other in order. They have a difference of 2 between every two numbers.
Consecutive odd numbers are odd numbers that follow each other in order. They have a difference of 1 between every two numbers.
Let's take your example: 1, 4, 9 are consecutive what?? They form an A.P!
Also, the second set: 2, 8, 18 neither forms an A.P nor are consecutive!
8 - 2 = 6
18 - 8 = 10
They don't have a common difference.
