Answer:
First number = 16
Step-by-step explanation
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
