Question

Daca suma a cinci numere pare consecutive este cu 3 472 mai mare decat al treilea numar , care sunt numerele ???

Answer 1

a+a+2+a+4+a+6+a+8=a+4+3472
5a+20=a+4+3472
4a=3472-4-20
4a=3448
a=3448/4=862

Answer 2

a + a + 2 + a + 4 + a + 6 a + 8 = 3 472 + a + 4
5 a + 20 = a + 4 + 3 472
5 a + 20 = a + 3 476
5 a - a = 3 476 - 20
4 a = 3 456
3 456 : 4 = 864 ( a )
864 + 2 = 866 b
864+4=868 c
864 + 6 = 870 d
865 + 8 = 872 e
