Here we're given four figures and we need to find a pattern so that we can draw the fifth figure.
00:05
So if you look at what's going on here, we started off with two blocks and then we went into five blocks and we have 10 blocks and then we have 4 by 4, 16, 17 blocks.
00:17
So that's a little bit tricky to find a pattern here.
00:20
But if you think about this as what if this is for n equals 1, 2, 3, 4, so on.
00:28
So if n is 1, and then add 1 to that, you get 2.
00:33
Notice that also this could be thought of as a 1 squared.
00:36
Then the next one we have 2 squared, plus another 1.
00:40
So the 2 squared would represent this block here...
