Answer:
3, 1, - 1, - 3, - 5
Step-by-step explanation:
using the recursive formula and f(1) = 3 , then
f(2) = f(1) - 2 = 3 - 2 = 1
f(3) = f(2) - 2 = 1 - 2 = - 1
f(4) = f(3) - 2 = - 1 - 2 = - 3
f(5) = f(4) - 2 = - 3 - 2 = - 5
first 5 terms are 3, 1, - 1, - 3, - 5

The value of a correlation coefficient ranges between -1 and 1.
The greater the absolute value of the Pearson product-moment correlation coefficient, the stronger the linearrelationship.
The strongest linear relationship is indicated by a correlation coefficient of -1 or 1.
The weakest linear relationship is indicated by a correlation coefficient equal to 0.
A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
