Answer:
10%
Step-by-step explanation:
First, get the drop in value by deducting the price this year from last year's price.
Value decrease=$52.00-$46.80=$5.20
To express it as a percentage, we divide it by the original price which was $52.00 then multiply by 100 hence the percentage decrease will be
Therefore, the price decreases by 10%
Step-by-step explanation:
just substitute the value of g(X) and f(X)
Check the forward differences:
-1 - 1 = -2
-7 - (-1) = -6
-25 - (-7) = -18
Notice how the differences appear to follow a geometric progression with common ratio 3. So if denotes the
th term in the given sequence, we seem to have
so that the general pattern for would be
Then the sequence is given recursively by
The first 10 terms in the sequence would be
1, -1, -7, -25, -79, -241, -727, -2185, -6559, -19681
