Question

Multiplii lui 3 curinsi intre 200 si 325

Answer 1

M3(200,325)={201+3k/k∈N, 0≤k≤41}

201 fiind primul multiplu de 3 ≥200.

L-am limitat pe k din

325>201+3k

3k<124

k<41,(3), k∈N ⇒ k≤41

Answer 2

201, 204, 209, 210, 213, 216, 219, 222, 225, 228, 231, 234, 237, 240, 243, 246, 249, 252, 255, 258, 261, 264, 267, 270, 273, 276, 279, 282, 285, 288, 291, 294, 297, 300, 303, 309, 312, 315, 318, 321, 324
