Givens

7 oz cost $2.38

15 oz cost $5.25

26 oz cost $8.58

Solution

7 oz cost $2.38

1 oz cost x This is a proportion. 3 quatities are known. Find x Cross multiply.

7/1 = 2.38/x

7x = 2.38

x = $0.34 dollars

15 oz cost 5.25

1 oz costs x

15.1/1 = 5,25 x Cross Multiply

15x = 5.25 * 1 Divide by 15

x = 5.25 / 15

x = $0.35

26 oz cost 8.58

1 oz cost x

26/1 = 8.38/x Cross Multiply

26x = 8.38 Divide by 26

x = 8.38/20

x = 0.32 dollars

Answer

7 oz cost 0.34

15 oz cost 0.35

26 oz cost 0.32

What are the next 4 terms to this sequence<br><br>2, 6, -4, 10, -14,

Kay [80]

Answer:

24, -38, 62, -100

Step-by-step explanation:

The recursive formula is a_n = a_(n-2) - a_(n-1)

so. we try this 4 times after the -14 term

a_3 = -4 = 2 - 6 = a_1 - a_2

...

a_6 = a_4 - a_5 = 10 - (-14) = 24

a_7 = a_5 - a_6 = -14 - (24) = -38

a_8 = a_6 - a_7 = 24 - (-38) = 62

a_9 = a_7 - a_8 = -38 - 62 = -100

a_10 = a_8 - a_9 = 62 - (-100) = 162
