Thank you for the reply!

No worries!

The answer seems to be correct. 

Thanks for answering. 

Only feedback is that I followed through with your solution. And the exact solution would be 11 and 2/3 percent

You cannot go over a path you have already taken.

Thanks!

The pattern is as follows:

2, 6, 12, 20.

For each tower, we can see we have the X² + X   - where X is the tower number.

So, let's say it was the 3rd tower.

So, substituting for the equation, we get:

3² + 3 = 12

If we check, that is true. The 3rd tower does have 12 blocks. 

Let's find the total for the 99th tower.

Total = 99² + 99 = 9900

Therefore, the 99th tower has 9900 blocks.

Yes, they are similar

Solution:

The scale factor is one-half. This is because we need to multiply \(\Delta\)SRQ * 2 to get to the other triangle. 

Example:

If the sides of a triangle were 1/3 the size of the other triangle, the scale factor would be 3.
