-4n + 5 is the algebraic form of an arithmetic sequence. What is its first term and common difference?

a1=1

- 4 (common difference)

Step-by-step explanation:

a1=-4*1+5=-4+5

a1=1

a2=-4*2+5=-8+5=-3

common difference=a2-a1=-3-1=-4

1 and -4.

Step-by-step explanation:

First term is when n = 1 so it is:

-4(1) + 5 = 1.

The common difference is the coefficient of n which is -4.

For example the 2nd term = -4(2) + 5 = -3.

Common difference =  2nd term - first term

= -3 -1

= -4.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
