The table below shows the number of shoppers at Jacob's store over a period of five months:

Olin [163]

We are given table

Month : 1 2 3 4 5

Shoppers: 50 250 1250 6250 3250

so, we have

first term =50

$a_1=50$

Second term =250

$a_2=250$

Third term =1250

$a_3=1250$

$a_4=6250$

$a_5=31250$

now, we can find ratios

$\frac{a_2}{a_1} =\frac{a_3}{a_2}=\frac{a_4}{a_3}=\frac{a_5}{a_4}=5$

we can see that all ratios are same and 5

so, this is exponential

so, option-D..........Answer
