If possoble, identify the common ratio or difference.
9, 13, 17, 21, ....
a. arithmetic
b. geometric
c. geometric
d. neither
Step 1 Fora sequence to be arithmetic sequence difference between consecutive terms must be equal.
Mathematically,
Consider the given sequence: 9,13,17,21,...
Step 2
Now check for common difference,
This proves that,
Therefore, it is arithmetic progression with common difference 4,
For the following exercises, determine whether the equation represents exponential growth, exponential decay, or neither. Explain.
