1. List the first 9 terms of the sequence defined recursively by = −2 ∙(−1 −1), with 1 = 2 and 2 = 3

2. Compute the value of ∑ 8^ =1> , where is the same sequence as in the previous question.

3. Is the sequence from question 1 arithmetic, geometric, or neither? Explain how you reach your conclusion.

4. Find the sum of the first 200 terms of the arithmetic sequence that begins: 12, 18, 24, …

5. Find the sum of the first 8 terms of the geometric sequence that begins: 12, 18, 27, …

6. Find the sum of the infinite geometric sequence that begins 1/12 ,1/18
,1/27 , ...

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.  

if you was gonna solve for a, a is a   < -12

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
