Answer:

a_5= 14

a_{20}= 80

a_{18}= 340

Step-by-step explanation:

Solving (a):

We have:

a_1=2 --- first term

d = 5 -2 = 3 common difference

The 5h term is:

a_n= a_1 + (n - 1)d

a_5= 2+ (5 - 1)*3

a_5= 14

Solving (b):

We have:

a_1 = 4 --- first term

d = 8 -4 = 4 common difference

The 20h term is:

a_n= a_1 + (n - 1)d

a_{20}= 4+ (20 - 1)*4

a_{20}= 80

Solving (c):

We have:

a_1 = 0 --- first term

d = 20 -0 = 20 common difference

The 18th term is:

a_n= a_1 + (n - 1)d

a_{18}= 0+ (18 - 1)*20

a_{18}= 340

There is a line that includes the point (2, 10) and has a slope of 1. What is its equation in
rjkz [21]

Answer:

The line is y=1x+8

Step-by-step explanation:

We can use point-slope form of a line to make an equation. Point-slope form is as follows:

y-y₁=m(x-x₁)

**The variables y₁ and x₁ are where we will plug in our given coordinates and the variable m is your slope.

1. Plug in the given info:

y-10=1(x-2)

2. Distribute the 1:

y-10=1x-2

3. Add 10 to both sides:

y=1x+8
