Answer:
The constant in the algebraic expression to represent the pattern below is 4.
Step-by-step explanation:
Imortant Tip:
Given the pattern
[tex]15,11,7,3,-1,...[/tex]
computing the differences of all the adjacent terms
[tex]11-15=-4,\:\quad \:7-11=-4,\:\quad \:3-7=-4,\:\quad \:-1-3=-4[/tex]
The difference between all the adjacent terms of the pattern is the same which is
[tex]d=-4[/tex]
Hence, the given pattern represents the Arithmetic sequence.
Therefore, the constant in the algebraic expression to represent the pattern below is 4.
