Regents Exam: Algebra I August 2016 (Problem 10 of 37)

The video tutorial explains how to determine the function that defines a given sequence, where F(6) equals -26. It first demonstrates a systematic approach by evaluating functions at X=6 to find the correct one. The tutorial then analyzes the sequence, noting its consistent decrease by -4, indicating a linear sequence with a slope of -4. The correct function is identified as the one with this slope.

How can we determine which function corresponds to the given sequence?

Why was the first function evaluated at X equals 6 successful in finding the answer?

What is the common difference in the given sequence?

What does the slope of the function represent in the context of the sequence?

What is the significance of the slope being -4 in the context of the sequence?
