Question

The sum of 5 consecutive even numbers is 100. What is the first number in this sequence?

Answer 1

Answer:

18 is the correct answer

Answer 2

Answer:

Let us take the first number = ' x '

Second number = ' x + 2 '

Third number = ' x + 4 '

Fourth number = ' x + 6 '

Fifth number = ' x + 8 '

If we add them, we get 100

( x ) + ( x + 2 ) + ( x + 4 ) + ( x + 6 ) + ( x + 8 ) = 100

5x + 20 = 100

5x = 80

x = 80 / 5

x = 16

First number = 16

Numbers are = 16 , 18 , 20 , 22 , 24
