Step-by-step explanation:
Sum of five consecutive number = 100
First consecutive number = (x )
Second consecutive number = ( x+1)
Third consecutive number = (x+2)
Fourth consecutive number = (x+3)
Fifth consecutive number = (x+5 )
(x )+ (x+1 ) + ( x+2 ) + ( x +3 ) +( x +4 ) = 100
5x + 10 =100
5x =100-10
5x = 90
x= 90/5
x=18
