Question

What is the 13th term of 2/9, 1/4, 2/7, 1/3 ...........?

Answer 1

Answer:

If you look at 1/8 and 2/7, the numerator is increased by 1 and the denominator is decreased by 1. However, the next number is 1/2. Looking at this number, you might feel as though there is no pattern as the numerator does not increase by 1 nor does the denominator decrease by 1. But, 1/2 can be written as 3/6 by multiplying both the numerator and denominator by 3. Now the pattern s evident as once again the numerator increases by 1 and the denominator decreases by 1. The last number is 4/5 in which the same sequence follows.
