Answer 1

Answers:

1st: -8

2nd: 14 + (k-1)(-8)

3rd: x=7 y= 22 z= -8

i did it :))

Answer 2

The difference (d) = - 8

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Arithmetic series : 14 + 6 + (–2) + (–10) + (–18) + (–26) + (–34)

2. What is the common difference d of the arithmetic sequence on which the series is based?

1st an 2nd element difference = 14 - 6 = 8

2nd and 3rd element difference = - 6 - 2 = -8

3rd and 4th element difference = - 2 + 10 = 8

4th and 5th element difference = -10 + 18 = 8

The difference (d) is 8 and it's negative because the series is lowering the previous value.

3. Proof of d = - 8

14 - 8 = 6

6 - 8 = - 2

- 2 - 8 = - 10

- 10 - 8 = - 18

- 18 - 8 = - 26

-26 - 8 = -34
