Question

1. Find the next three terms in the sequence.
3, 12, 21, 20, . . .

2. Identify the sequence as arithmetic, geometric, or neither.
1.6, 0.8, 0.4, 0.2, . . .

3. 5x 3 n

4. Use the function rule f(x) - x (x) |-1| x. Find the output f(2).

Answer 1

Wrong

Answer 2

1. Find the next three terms in the sequence.
3, 12, 21, 20, . . .

A. 40, 50, 60
B. 38, 46, 54
C. 39, 48, 57
D. 36,32, 39

Your answer is not there

Answer 3

I think there is a typo in #1
it shows a common difference of 9 for the first 3 terms, but then the 20 does not match. I think that 20 should be 30
(of course the bot is not smart enough to catch that)


so actually in #1 , the next 3 terms for
3, 12, 21, 30, . . . would be 39, 48, and 57

(the common difference of this arithmetic sequence is 9)

Answer 4

yes, bot, that's what I said. Why are your repeating it ???

Answer 5

1. The next three terms are 9, 28, 37.
2. This is a geometric sequence, with a common ratio of 1/2.
3. This is not a sequence, but rather an expression.
4. f(2) = 2 * (2) * |-1| * 2 = 8.

Answer 6

I apologize. Can you please clarify what I did wrong and provide the correct answers?

Answer 7

I apologize for the error in my previous response. The correct answer is option C. The next three terms in the sequence are 39, 48, and 57.

2. Identify the sequence as arithmetic, geometric, or neither.
1.6, 0.8, 0.4, 0.2, . . .

This is a geometric sequence, with a common ratio of 1/2.

3. 5x + 3n

This is an expression, not a sequence.

4. Use the function rule f(x) - x (x) |-1| x. Find the output f(2).

f(2) = 2 * (2) * |-1| * 2 = 8.

Answer 8

You are correct. Thank you for pointing out the mistake in my answer for #1. The correct sequence is 3, 12, 21, 30, and the next three terms are 39, 48, and 57. The common difference of this arithmetic sequence is 9.

Answer 9

I apologize for repeating what you already said. Thank you for bringing the mistake to my attention.
