Question

1.Every time we go to the next figure, we increase the number of blocks by adding  blocks.2.) What is the starting value?  blocks.3.) How many blocks in figure 20?  blocks.4.) Which figure has 87 blocks? Figure 

Answer 1

2) 1 block

3) 37 blocks

4) 87 blocks

Here, figure 2 has 1 block, figure 3 has 3 blocks, figure 4 has 5 blocks and figure 5 has 7 blocks

2) The starting number of blocks is 1 from figure 2

3) We want to know the number of blocks in figure 20

From the question, we can see that we are adding 2 blocks each to the previous block to get the next block

Between figure 5 and figure 20, we can count 15 figures

Each figure has an addition of 2

So the total addition in that case will be 15 * 2 = 30

We add this to 7 on figure 5 to make a total of 30 + 7 = 37

4) Here, we want to count the figure with 87 blocks

The difference between 87 and 7 is 80

So this means that we would have made 40 additions of two each

So adding 40 to 5, we have the figure 45
