Question

What is the interquarite range of 12 16 20 24 28 32 36 40 44 48

Answer 1

Is the answer 20?
That's how I got the answer.
The sequence number is already arranged in ascending order. So what I did is Separate the sequence number into 2 part.
First part is the first 5 digits while the second part is the last 5 digits. Then, choose the middle number in each of the 5 digits. Use the larger number to minus the smaller number.
40-20 =20
