Arithmetic Reasoning Question

In working as an ASVAB tutor, I present numerous lessons on Arithmetic Reasoning.  I wrote a book to coincide with my ASVAB prep course.  The book is called The ASVAB Tutor’s Arithmetic Arithmetic Reasoning Study Guide.  One of the numerous topics is the topic of patterns and sequences.  Today I present an Arithmetic Reasoning question on patterns and sequences involving fractions.

The question is:

What come next in the pattern?

1/6, 1/12, 1/18, _____

  1. 1/20
  2. 1/22
  3. 1/24
  4. 1/30

Do you know what fraction comes next in this pattern?

I will present the answer and explanation in two days.
