Answer:
-1/4
Step-by-step explanation:
Given sequence is:
1/2, 1/4 , 0, ...
In order to find the common difference in the terms of a sequence, the preceding term is subtracted from the next term.
For example in the given sequence:
first term will be subtracted from second term and second term will be subtracted from third term
So,
[tex]\frac{1}{4}-\frac{1}{2} \\=\frac{1-2}{4}\\ =-\frac{1}{4}\\ Similarly,\\=0-\frac{1}{4} \\=-\frac{1}{4}[/tex]
The common difference is - 1/4 ..
