study the numeric pattern and write an expression to describe the pattern
-2 , -4 , -6 , -8
The pattern is decreasing by 2 with each term.
The expression to describe the pattern is:
-2n
where n represents the position of the term in the pattern.
To describe the pattern, we can observe that each number in the sequence is decreasing by 2. We can write an expression to describe the pattern as follows:
n = -2 - (2 * (k-1))
Where n is the nth term in the sequence and k represents the term number.
