Identify the common difference 10,20,30,40 ..

10

Step-by-step explanation:

Hello there, 10 is your common difference. the numbers consecutively go up 10. You can also check by doing the third term minus the second or the 4th minus the 3rd.

3x3 = 9 and 2x2 = 4

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)
