Find the second, fifth, and ninth terms of a sequence where the first term is 65 and the common difference is -7.
Trava [24]
There are multiple ways to do this.

The easiest is to just continuously subtract 7 from 65 the numbers of times needed.

But most math teachers will have you use the equation ar^n-1 where a= the first term (65), r=ratio (-7), and n=the term you need (second, fifth, and ninth). 

So to solve you just plug your values in as so
AR^n-1

(65)(-7)^2-1(65)(-7)^5-1
(65)(-7)^9-1

You have conducted pre- and post-test measures of the effectiveness of pay raises on employee productivity, measured as net $ sa
lord [1]

Answer:

2000 USD

Step-by-step explanation:

a. Difference for employee 1: 14000 - 10000 = 4000

b. Difference for employee 2: 11000 - 12000 = -1000

c. Difference for employee 3: 13000 - 11000 = 2000

d. Difference for employee 4: 10000 - 8000 = 2000

e. Difference for employee 5: 12000 - 9000 = 3000

The absolute mean difference of 5 employees is

(4000 - 1000 + 2000 + 2000 + 3000)/5 = 10000/5 = 2000

So the average net increase of each employed in the past month is 2000 USD
