Buna

a I----I

b I----I+1

c I----I+2        => 30

d I----I+3

e I----I+4

30 - 10 = 20

20 : 5 = 4 ( a )

a= 4

b=5

c=6

d=7

e=8

VERIFICARE:

Answer 2

a ___

b ___ + 1

c ___ + 2 =》30

d ___ + 3

e ___ + 4

30 - (1 + 2 + 3 + 4) = 30 - 10 = 20

a = 20 : 5 = 4

b = 4 + 1 = 5

c= 4 + 2 = 6

d = 4 + 3 = 7

e = 4 + 4 = 8

Verificare:

a + b + c + d + e = 30

4 + 5 + 6 + 7 + 8 = 30 =》sunt nr. consecutive

a = 4

b = 5

c = 6

d = 7

e = 8
