Question 26

image/svg+xml 1/5 11/4 -10 -29/8 -19/7 -47/20 ?
What is the next number in this sequence?

Explanation

In this sequence there are actually two sequences. 1 sequence for the numerators and one sequence for the denominators. The following transformation applies to the sequence for the denominators : +9
This creates the following sequence: [2, 11, 20, 29, 38, 47, 56]

The following transformation applies to the sequence for the numerators: -6
This creates the following sequence: [10, 4, -2, -8, -14, -20, -26]

Take a good look at how to rewrite the fractions in the series to recognize the pattern.
For example, 1/5 can be rewritten as 2/10
