Question

The sum of four cosecutive even number is 60. Find smallest of four numbers ​

Answer 1

Step-by-step explanation:

Solution:

Given:

The sum of four consecutive even number is 60

Calculation:

Let be assume the number is n, n + 2, n + 4, n + 6

⇒ n + n + 2 + n + 4 + n + 6 = 60

⇒ 4n + 12 = 60

⇒ 4n = 48

⇒ n = 48/4 = 12

∴ The required result will be 12.

Answer 2

Answer:

144, 196,256, and 324

Step-by-step explanation:

Let x = the first even number

Let (x+2)= the second even number

Let (x+4)= the third even number

Let (x+6)= the fourth even number

x+(x+2)+(x+4)+(x+6)=60 [Given]

4x+12=60 [Combine like terms]

4x=48 [Subtract 12 from each side]

x=12 [Divide both sides by 4]

x+2=14

x+4=16

x+6=18

12^2=144

14^2=196

16^2=256

18^2=324

Answer: 144, 196,256, and 324
