Based on these first few terms, we can deduce that the next term is computed by switching the sign of the previous one, and multiplying it by 3: we start with -1, we switch the sign (1) and multiply by 3 (3); then again we switch the sign (-3) and multiply by 3 (-9), and so on.
Since switching sign is the same as multiplying by -1, we can compute every next term by multiplying the previous one by -3:
So, the recursive formula is
because it states precisely that the next term is -3 times the previous one.
The question is sort ..
Answer:
Step-by-step explanation:
The points are (6,39) and (-5,-49)
We need to find the equation of this line.
The slope is given by:
We use the formula:
We substitute the point (6,39) and m=8 to get:
We expand to obtain:
