1. What is the 8th term of the arithmetic sequence with a first term of 7 and a common difference of -3?

2. What is the 4th term of the recursive sequence defined by (image attached)

1) -14

2) a4 = 61

Step-by-step explanation:

8th term = 7 + (8-1)(-3)

= 7 -21

= -14

2) a2 = 2(5)+3 = 13

a3 = 2(13)+3 = 29

a4 = 2(29)+3 = 61

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
