What is the explicit formula for the sequence {3, 8, 13, 18,...}? 1.an = 3 + 02-1
2.an = 3 +5,1
3.an = 3 - 5(n - 1)
4.an = 3 + 5(n - 1)

An = 3 + 5(n-1)

Step-by-step explanation:

You can use guess and check until you see the right sequence.

A1 = 3 + 5 (1 - 1) = 3 + 5(0) = 3

A2= 3 + 5 (2-1) = 3 +5(1) = 8

A3 = 3 + 5(3-1) = 3 +5(2) = 13

...

An = 3 +5 ( n - 1 )

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
