Fan and Medal!

Answer 1

I know what the 'alg1' would look like, I don't know how to put in into a equation. on 'alg2,' I'm completely lost.

Answer 2

On the first problem, do you think that 4 dots are added to each diagram to get the next diagram?

Answer 3

yes

Answer 4

In your drawing, how many dots are in the 6th term?

Answer 5

6 in each line,1 in the middle

Answer 6

Look at the algebraic expressions given as answer options.

In the options, replace x by 6 and determine which option gives 21 when you do that.

Answer 7

A?

Answer 8

That is what I got.

Answer 9

ohhhh

Answer 10

On the second problem, the first term of the geometric sequence is given to be 4. The common ratio is 5.

So, the sequence starts out:

4, 4*5, which is 4, 20, ...

Answer 11

What are the next three terms?

Answer 12

@Catpidigm

Answer 13

100, 500, 2500. Sorry had to brb...

Answer 14

4, 20, 100, 500, 2500, ,,,

There are two options with those beginning terms.

Answer 15

20 *5 = 100, 100 *5 = 500... The slope is *5, right?

Answer 16

The common ratio is *5, yes.

Answer 17

yay! :) and b and d are out,

Answer 18

Of the two answer options with first 5 terms of 4, 20, 100, 500, 2500, ,,,

only one of them has the first term, a (1) given to be 4.

Do you see it?

Answer 19

one is 5* 4, the other is 4 * 5, so C is right, if that's correct.

Answer 20

Thank you so much :) I got an 100!

Answer 21

Great news.

Look, the problem mentions recursive formula but does not give any of those in the options. I assume we can ignore the recursive formula.

Answer 22

You're welcome.

Answer 23

Got it :)
