Suppose the inexperienced squares have a aspect size of 1. There are 6 small squares of dimension 1, then 5 squares of dimension 2 (proven beneath), then 1 sq. of dimension 3, and naturally your complete determine is 1 sq. of dimension 4. In whole that’s 6 + 5 + 1 + 1 = 13 squares.
9:40 Puzzle 6
What are the following 2 lacking numbers within the sequence?
7688, 2688, 768, 336, __, __
The product of the digits of every quantity would be the subsequent quantity.
7x6x8x8 = 2688
2x6x8x8 = 768
7x6x8 = 336
3x3x6 = 54
5×4 = 20
So the following two numbers are 54 and 20.

Quantity the squares from 1 to 10, and take into consideration every sq. because the node of a graph. Join nodes if a knight can journey between the corresponding squares. The issue is then reworked into the next graph, the place a knight can transfer to adjoining nodes.
Now it turns into clear that 5 is the important thing place the place a knight will be “parked” to permit all the opposite knights to go. So now the technique is evident:
–switch the knights from 1, 2, 3 into the positions 6, 7, 8, which clears the trail for the knight on 5 to go straight again to 1
–we now have to switch the black knight on 8 to sq. 2. So let’s transfer the white knights again to nodes 2 and three, which permits a transparent path for the knight on 8 to get parked on 5
–transfer the white knights into nodes 6 and seven, which clears the trail for the black knight on 5 to go to sq. 2
–transfer one white knight to sq. 3 and the opposite to sq. 5
The puzzle requires an unimaginable 40 strikes!
black knight from 3 to eight
k3-4-6-7-8
white knight 2 to 7
k2-3-4-6-7
white knight 1 to six
k1-2-3-4-6
