The sum of three consecutive numbers is 477. what is the 3rd number?

160

Step-by-step explanation:

Consecutive numbers have a difference of 1 between them.

Let n be the first number then n + 1 and n + 2 are the second and third numbers. Summing them gives

n + n + 1 + n + 2 = 477, that is

3n + 3 = 477 ( subtract 3 from both sides )

3n = 474 ( divide both sides by 3 )

n = 158

The 3 consecutive numbers are 158, 159, 160

The third number is 160

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
