Question

Suma a 5 nr consecutive pare este 100 afla nr

Answer 1

q+r+y+g+u=100
q |----|
r |----|-|-|
y |----|-|-|-|-| )100
g |----|-|-|-|-|-|-|
u |----|-|-|-|-|-|-|-|-|

1*20=20
100-20=80
80:5=16(q)
16+2=18(r)
18+2=20(y)
20+2=22(g)
22+2=24(u)

Answer 2

aceasta problema se rezolva prin metoda segmentelor:
a,b,c,d,e=>numere consecutive
b=a+1
c=b+1
d=c+1
e=d+1

a+b+c+d+e=100
____________________________
a=?,b=?,c=?,d=?,e=?
a |—-------|
b |—-------|+1
c |—-------|+1+1
d |—-------|+1+1+1
e l—-------|+1+1+1+1

100-10=90(5 parti egale cu a )
90:5=16(a)
16+1=17( b)
17+1=18(c )
18+1=19( d)
19+1=20(e )
