Answer:
402
Step-by-step explanation:
Given, the 4 figures, you can see that the number of squares in each figure is 2+2n, where n is what figure it is.
We can confirm that by checking figure 1, which has 2+2*1 = 4 squares, and figure 2, which has 2+2*2 = 6 squares. You can do it with figures 3 and 4, but in my opinion, that would be unnecessary.
Now, to find the number of squares in figure 200, just plug in 200 for n, and we get 2+2*200 = 402.
Therefore, figure 200 has 402 squares.
