Find the sum of the first 6 terms of 3 - 6 + 12 + …

Step-by-step explanation:

The sequence above is a geometric sequence.

The common ratio (r) =

The common ratio < 1, therefore, the formula for the sum of nth terms of the sequence would be:

a1 = 3

r = -2

n = 6

Plug in the values into the formula

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
