I need help finding the function rule for this problem if anyone could help it would be much appreciated Heres the problem: N--- 1 2 3 4 5 6
F(n) 1 -1 -4 -7 -10 -13
I did a scatterplot of your data. Although not linear, it was pretty close. Linear regression analysis put the line of best fit to:
$\displaystyle y = -2.85714x + 4\frac{1}{3}$
The correlation coefficient (r) = .9983374885, so that's pretty close to 1.
Does this help?
