EXAMPLE

At first the sums of the digits look like a jumble of figure, but choose at random any sequence of numbers and multiply them by 4 and you will see the pattern emerge of two interlinked columns of digits in descending order.

2160*4 = 8640 -- 8+6+4+0 = 18 ----------- 1+8 = ---- 9
2161*4 = 8644 -- 8+6+4+4 = 22 ----------- 2+2 = 4
2162*4 = 8648 -- 8+6+4+8 = 26 ----------- 2+6 = ---- 8
2163*5 = 8652 -- 8+6+5+2 = 21 ----------- 2+1 = 3
2164*4 = 8656 -- 8+6+5+6 = 25 ----------- 2+5 = ---- 7
2165*4 = 8660 -- 8+6+6+0 = 20 ----------- 2+0 = 2
2166*4 = 8664 -- 8+6+6+4 = 24 ----------- 2+4 = ---- 6
2167*4 = 8668 -- 8+6+6+8 = 28 -- 2+8=10 - 1+0 = 12168*4 = 8672 -- 8+6+7+2 = 23 ----------- 2+3 = ---- 5
