Question

Quantos são os multiplos de 6 compreendido entre 101 e 1001?

Answer 1

102,108,114,120,126,132,138,144,150,156,162,168,174,180,186,192,198;
204,210,216,222,228,234,240,246,252,258,264,270,276,282,288,294,300.306,312,318,324,330,336,342,348,354,360,366,372,378,384,390,396,402,408,414,420,426,432,438,444,450,456,462,468,474,480,486,492,498,504,510,516,522,etc...
(Não tenho tempo para fazer todos, desculpa)

Answer 2

996 = 102 + (n -1 ) 6
996 - 102 = 6n - 6
894 + 6 = 6n
900 = 6n
900/6 = n
150 = n

Logo, há 150 multiplos de 6, entre 101 e 1001
