Write down in terms of n an expression of the nth terms?

A. nth term = 4 + (n - 1) -3

B. nth term = -7 + (n - 1) -5

Step-by-step explanation:

A. 4, 1, -2, -5, -8

First term, a = 4

Common difference, d = 1 - 4 = -3

nth term = a + (n-1)d

nth term = 4 + (n - 1) -3

B. -7, -12, -17, -22, - 27

First term, a = -7

Common difference, d = -12 - (-7)

= -12 + 7

= -5

nth terms = a + (n - 1)d

nth term = -7 + (n - 1) -5

correct answer:

b.(19,-2)

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
