Salut,
Notam numerele astfel: x, x + 2, x + 4.
x + x + 2 + x + 4 = 252 <=> 3x + 6 = 252 <=> 3x = 252 – 6 <=> 3x = 246 <=> x = 246 : 3 <=> x = 82
x = 82
x + 2 = 82 + 2 <=> x + 2 = 84
x + 4 = 82 + 4 <=> x + 4 = 86
Numerele cerute sunt: 82, 84, 86.
p /-----/
d /-----/ ²
t /-----/ ⁴
252 – (2 + 4) = 252 – 6 = 246 (3 parti egale cu numarul mic)
246 : 3 = 82 (primul numar)
82 + 2 = 84 (al doilea numar)
82 + 4 = 86 (al treilea numar)
