Answer:

$a_{n}$ = 3n + 77

Step-by-step explanation:

The nth term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 80 and d = a₂ - a₁ = 83 - 80 = 3 , then

$a_{n}$ = 80 + 3(n - 1) = 80 + 3n - 3 = 3n + 77

Answer:

d = √5 ≈ 2.24

Step-by-step explanation:

B is located at (1, 3) and B' is located at (3, 4)

Distance formula:

[tex] d = \sqrt{(xB' - xB)^2 + (yB' - yB)^2}[\tex]

replacing with the coordinates of the points:

[tex] d = \sqrt{(3 - 1)^2 + (4 - 3)^2}[\tex]

[tex] d = \sqrt{4 + 1}[\tex]

d = √5 ≈ 2.24
