Find the first six terms of the sequence. a1 = 4, an = an-1 + 8

The first 6 terms are 4,12,20,28,36,44

Step-by-step explanation:

So we have the recursive sequence

.

If you try to dissect what this really means, it becomes easy.  

Pretend is a term in your sequence.

Then is the term right before or something like means the term right after.

So it is telling us to find a term all we have to is add eight to the previous term.

So the second term is 4+8=12.

The third term is is 12+8=20.

The fourth term is is 20+8=28.

The fifth term is is 28+8=36

The sixth term is is 36+8=44.

Now sometimes it isn't that easy to see the pattern from the recursive definition of a relation. Sometimes the easiest way is to just plug in. Let's do a couple of rounds of that just to see what it looks like.

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
