Question

halla 3 numeros impares consecutivos cuya suma valga 69

Answer 1

Los números, 2x + 1, 2x + 3, 2x + 5

2x + 1 + 2x + 3 + 2x + 5 = 69

2x + 2x + 2x + 1 + 3 + 5 = 69

6x + 1 + 3 + 5 = 69

6x = 69 - 5 - 3 - 1 

6x = 60

x = 60/6

x = 10

2x + 1 = 2 (10) + 1 = 20 + 1 = 21
2x + 3 = 2 (10) + 3 = 20 + 3 = 23
2x + 5 = 2 (10) + 5 = 20 + 5 = 25

Respuesta : Los números son : 21, 23 y 25
