Given the sequence 31,24,17,10......
What would the 11th term of the sequence be?
The 11th term of the sequence is
Scientific Calculator

Answers

Answer:

-39

Step-by-step explanation:

This sequence follows the pattern of subtracting 7 each time. We can prove this:

31 - 7 = 24, 24 - 7 = 17, 17 - 7 = 10

So if we were to continue to the 11th term, we would subtract 7 more times.

1. 10 - 7 = 3

2. 3 - 7 = -4

3. -4 - 7 = -11

4. -11 - 7 = -18

5. -18 - 7 = -25

6. -25 - 7 = -32

7. -32 - 7 = -39

The 11th term in the sequence would be -39.

Please show work I need it please and thanks fir Hu ever answers it

Answers

Answer:

x³ - 2x² + 9x - 18x³ - 5x² + 3x + 9

Step-by-step explanation:

Zero's

x = -3i, x = 2 and the third zero is x = 3i

Polynomial is:

(x + 3i)(x - 3i)(x - 2) =(x² - 9i²)(x - 2) =(x² + 9)(x - 2) =x³ - 2x² + 9x - 18

Zeros:

x = 3, x = 3, x = -1

Polynomial is:

(x - 3)(x - 3)(x + 1) = (x² - 6x + 9)(x + 1) =x³ + x² - 6x² - 6x + 9x + 9 =x³ - 5x² + 3x + 9
