What is the value of the fourth term in a geometric sequence for which a to the 1 = 30 and r = 1/2

1.175

Step-by-step explanation:

You could use the formulas but you can just divide 30 by 2, or multiply it by one half same thing really, 4 times. 30/2 = 15, 15/2 = 7.5, 7.5/2 = 3.75, 3.75/2 = 1.175

dont understand

step-by-step explanation:

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.
