Could someone please help me with part d) of this question? http://i.imgur.com/kCV6O8M.jpg

Answer 1

\(\large \text{Third iteration : }19 = 3 + 8\times 2\)

Answer 2

that makes the smallest possible number after second iteration to be : \(38\)

Answer 3

continue the same in second iteration also

Answer 4

\(\large \text{Second iteration : }38 = 20 + 9\times 2\)

Answer 5

smallest possible number after first iteration : \(209\)

Answer 6

\(\large \text{First iteration : }209 = 191 + 9\times 2\)

Answer 7

so, the required smallest number is : \(1919\)

Answer 8

it takes exactly 3 iterations,
and it does require exactly 3 iterations
