Can somebody check my math before I submit it? Thanks.

1. Answer: Arithmetic Sequences
2. Answer: 60, 66, 72, 78, ...
3. Answer: t(n + 1) = t(n) + 6, t(1) = 60
4. Answer: Geometric Sequence
5. Answer: 3,000,000 , 3,120,000 , 3,444,800, ...
6. Answer: t(n + 1) = t(n) + 1.04 , t(1) = 3,000,000

all but 6

t(n) = 3,000,000(1.04)^n

#6 is also correct, since they asked for recursion.

Certainly! I can help you check your math. Let's go over each question and see if the answers are correct.

1. Arithmetic Sequences:
To check if a sequence is arithmetic, we need to verify if the difference between consecutive terms is constant. So, to check your answer, subtract each term from the next term and see if you get the same result each time. If the differences are consistent, then it is an arithmetic sequence.

2. The sequence you provided is 60, 66, 72, 78, ... To find the difference between each term, we subtract 60 from 66, 66 from 72, and so on. If the differences are all the same, then you are correct that it is an arithmetic sequence.

3. The equation you provided, t(n + 1) = t(n) + 6, t(1) = 60, is the recursive formula for an arithmetic sequence. This formula states that each term is obtained by adding a constant difference (in this case, 6) to the previous term. If the first term (t(1)) is indeed 60 and each subsequent term follows the given formula, then your answer is correct.

4. Geometric Sequence:
To check if a sequence is geometric, we need to determine if the ratio between consecutive terms is constant. Divide each term by the previous term and see if you get the same result each time. If the ratios are consistent, then it is a geometric sequence.

5. The sequence you provided is 3,000,000, 3,120,000, 3,444,800, ... To find the ratio between each term, divide the second term by the first, the third term by the second, and so on. If the ratios are all the same, then you are correct that it is a geometric sequence.

6. The equation you provided, t(n + 1) = t(n) + 1.04, t(1) = 3,000,000, is not a geometric sequence. This equation represents an arithmetic sequence since each term is obtained by adding a constant difference of 1.04 to the previous term. Double-check your answer to see if you might have made a mistake.

Once you have checked each question, you should have a better understanding of whether your answers are correct.
