Let me break this down for you.

Polly walks across the street to buy a cracker (singular)

The sellers of the crackers only have 1 left to sell and there is a long line out the door.

Unless the owners have more frackers readily available to continue to sell, Polly will NOT get a cracker unfortunately.

Hope this helps! :)

Answer:

Find the explicit from for the sequence $t_n=t_{n-1}+4,t=6$ :

$a_n=4n+2$

This next question I edited a bit. Your question just says find the four terms. I'm assuming they meant the first four. I also changed the c to an $a$ .

Find the first four terms of the sequence given by: $a_n=n a_{n-1}-3,a_1=2$ :

a) 2,1,0.-3

You might want to read that second question again because there is errors in the question or things that don't really make sense. I made my own interpretation of the problem based on my own mathematical experience.

Step-by-step explanation:

So your first question actually says that you can find a term by taking that term's previous term and adding 4.

So more terms of the sequence starting at first term 6 is:

6,10,14,18,....

This is an arithmetic sequence. When thinking of arithmetic sequences you should just really by thinking about equations of lines.

Let's say we have this table for (x,y):

x | y

----------

1 6

2 10

3 14

4 18

So we already know the slope which is the common difference of an arithmetic sequence.

We also know point slope form of a line is $y-y_1=m(x-x_1)$ where m is the slope and $(x_1,y_1)$ is a point on the line. You can use any point on the line. I'm going to use the first point (1,6) with my slope=4.
