The sum of four consecutive odd numbers is 80 find the number

Let the numbers are

x, (x+2), (x-2) and (x+4)

Step-by-step explanation:

x + x +2 +x - 2+x+4 = 80

4x +4 = 80

4x =80-44x = 76

4x = 76

x = 76/4

x = 19x

x=19

(x+2) =19+2=21

(x-2) = 19-2=17

(x+4)=(19+4)=23

hope it helps

mark me brainliest pls

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

maya’s expression will generate the wrong sum because she violated the commutative property.
