Question

Sum of five consecutive numbers is 180. Find t
Sum of first and last number.​

Answer 1

Answer:

72

Step-by-step explanation:

let the first number be x.

Then the other numbers are (x + 1), (x + 2), (x + 3), (x + 4)

It says,

x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 180

⇒ x + x + 1 + x + 2 + x + 3 + x + 4 = 180

⇒ 5x + 10 = 180

⇒ 5x = 180 - 10

⇒ x = 170/5 = 34

The last of the five numbers is x + 4 = 34 + 4 = 38

34 + 38 = 72

I hope it helps you

please mark me as brainy please

Step-by-step explanation:

Hi ,

Let x , x + 2 , x + 4 , x + 6 , x + 8 are

five consecutive even numbers.

According to the given problem,

Sum of these five consecutive even

numbers = 200

x + x + 2 + x + 4 + x + 6 + x + 8 = 200

5x + 20 = 200

5x = 200 - 20

5x = 180

x = 180/ 5

x = 36

Therefore 5 consecutive even

numbers are

36 , 38 , 40 , 42 , 44

Next set of even numbers are

( 46 , 48 , 50 , 52 , 54 )

I hope this helps you.
