Q
Se da sirul: 5, 2, 8, 3, 11, 4, 14, 5,
17, 6, x, y
Calculeaza suma: x + y
(ajutor: descopera cele doua siruri
combinate in sirul dat)
Correct answer: answer number 1 - 27
x = 20, y = 7
x + y = 27
Cele doua siruri combinate in sirul
dat sunt:
1) primul sir: 5, 8, 11,
14, 17, x
x = 17 + 3 = 20
2) al
doilea sir: 2, 3, 4, 5, 6, y
y = 7
