Question

What is the next fraction in the sequence 19/20,4/5,13/20,1/2

Answer 1

The next fraction in the sequence is 7/20

Change all of your denominators to 20

The sequence is now:
19/20, 16/20, 13,20, 10/20

19-16= 3
16-13= 3
13-10= 3

So the difference is 3, now do 10-3=7

Add your denominator and you get 7/20.
