Question

If you write the function as a sequence, what would be the

common difference?
Destinee inherited a book of stamps from her grandmother.
She adds new stamps to the book every year. The total
number of stamps in the book is a function of the number of
years since Destinee started adding to it. The function is
linear
Enter the answer in the box.
Here are some ordered pairs in the function.
d =
{(2,213), (4,219), (7,228)}

Answer 1

9514 1404 393

Answer:

3

Explanation:

The common difference of an arithmetic sequence is the slope of the equation that describes it. The slope formula is useful in this case:

m = (y2 -y1)/(x2 -x1)

m = (219 -213)/(4 -2) = 6/2 = 3

The common difference of the corresponding arithmetic sequence is 3.
