The average of six consecutive odd numbers is 61. What is the difference between the highest and lowest numbers:

Let's 6 consecutive odd numbers are:

3,5,7,9,11,13

Lowest term is 3 and highest is 13

13-3=10

So difference of 10 will remain the same in the consecutive series numbers.

Look at this series: 53, 53, 40, 40, 27, 27, . . .

What number should come next ?

What number should come next ?

In this series, each number is repeated, then 13 is subtracted to arrive at the next number.

Rule = (1st number), (1st number), (1st number - 13 = 2nd number), (2nd number repeat), (2nd - 13 = 3rd number), (3rd number repeat)....

The series is 53, 53, 40, 40, 27, 27...

(53),(53 - 13 = 40), (40), (40 - 13 = 27) (27), (27 - 13 = 14), (14)...

So the answer is 14..
