The pattern is to divide by three each time. For the last operation, 
Example Question #183 : Number Series*
Give the missing term in the following sequence:
Each element, from the third element on, is equal to the sum of the previous two. For example:
The next element is the sum of 12 and 19:
Continuing the sequence, we confirm this:
Example Question #184 : Number Series*
Give the missing term in the following sequence:
To get each term, add an amount to the previous term; the amount added decreases by one each time, as seen below.
Add 2 to get the next term:
Continuing, we see that this is correct:
Example Question #186 : Number Series*
Give the missing term in the sequence:
The sequence is formed by adding consecutive perfect squares to each successive term, as seen below:
The next term is found by adding the square of 6:
Continuing, we can confirm that this is correct:
Example Question #187 : Number Series*
Give the missing term in the following sequence:
The elements given are all one greater than successive powers of 2:
The next element is one greater than the sixth power of 2:
the correct response. Continuing, we can confirm that this is the correct pattern:
Example Question #185 : Number Series*
Give the missing term in the following sequence:
Both the numerator and the denominator are increasing by 3:
The missing term is therefore
Continuing, we confirm this is correct:
