Step-by-step explanation
In a linear relationship, the y-values have equal differences. and
In an exponential relationship, the y-values have equal ratios.
so
Step 1
find the common difference ( if there is )

we can see the diffrence is not the same, so
it is not liear
Step 2
check the common ratio

so, the ratio is common,
therefore, the answer is
Exponential
