I think this is the answer: 14% of 57$= 7.98$.
57$ - 7.98$= 49.02$.
her tip is 7.98$.
We are given
sequence is 2 , 4 , 8 ,16 , 32 , .....
Firstly , we will check whether it is geometric sequence
Checking geometric sequence:
We will find common ratio between successive terms
and then we check whether they are equal
r1=(second term)/(first term)

r2=(third term)/(second term)

r3=(fourth term)/(third term)

r4=(fifth term)/(fourth term)

we can see that all four ratios are same

so, this is geometric sequence
Calculation of general term:
We got
common ratio is

Let's assume
number of terms is n
first term is 2

now, we can use formula

we can plug values
and we get
