What is the value of the unknown number in the verbal description? 5 times the sum of 12 and a number is 80 a. 4 b. 1 c. 16 d. 28

12 + 4 = 16

16 x 5 = 80

A. 4

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.
