What is the explicit formula for the arithmetic sequence 4/5, 29/30, 17/15, 13/10. answer is d on edg an = 4/5 + 1/6(n-1)

Step-by-step explanation:

The explicit formula is given by:

Where a is the first term (4/5) and d is the common difference (the difference is any 2 terms). So to find d:

29/30 - 4/5

29/30 - 24/30

5/30

1/6

d = 1/6

Now putting them into the formula:

The last answer choice is right.

answer: 2/4

step-by-step explanation:

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
