John’s weight loss for each week of the month is 5lbs. , 2.5lbs, and 2.5 lbs. he gained 3.5 lbs the last week. if john originally weighed 198 lbs, how much does he weigh know?

weight loss is negative weight gain is positive

198 -5 -2.5 -2.5+3.5 = 191.5 lbs

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
