Answer:
Decay
since 0.292 is less than 1
% rate of decrease
1 - 0.292 = 0.708
70.8%

Step-by-step explanation:
We have the sequence
{
−
16
,
4
,
−
1
,
⋯
}
By looking at the first three terms of the sequence, we can already see a pattern.
Starting at -16, each term has its sign reversed, and is divided by 4.
Hence the sequence can be written as:
{
−
16
,
−
16
(
−
1
4
)
,
−
16
(
−
1
4
)
2
,
⋯
}
So the formula for the
