Question

One number in the following series does not fit in with the pattern set by the others. What should that number be?
1/1000 1/100 1/10 0 1/10 10

Answer 1

It looks like the pattern is 1/10ⁿ starting with n = 3, and decreasing n one unit at a time.

 

1/1000

1/100

1/10

 

The next few numbers should be

 

1/1 = 1

1/0.1 = 10

1/0.01 = 100

etc.

Answer 2

Could be either 0 - its numerator is not 1

Or it could be 10 - it does not have a denominator and its numerator is 10.
