Use the sequence: 1,2,4,8... B. Write a rule for the sequence.
A
B
C
B
B
All are correct, but the last one is C for me which is 13 21 34.
I agree with both of you because also for me the last one is c. - 13, 21, 34. I made 100%.
1. Identify each sequence as arithmetic, geometric, both, or neither.
7, 9, 11, 13…
A- arithmetic
2. Identify each sequence as arithmetic, geometric, both, or neither.
2, 1, 1/2, 1/4….
B- Geometric
3. Write a rule for the sequence.
1, 2, 4, 8,…
C- Start with 1 and then multiply by 2 repeatedly.
4. Write a rule for the sequence.
50, 40, 30, 20,…
B start with 50 and then add -10 repeatedly.
5. Find the next three terms in the sequence.
1, 1, 2, 3, 5, 8….
C- 13, 21, 34.
You will add 1+1=2. 1+2=3. 2+3=5. 3+5=8
So then 5+8=13. 8+13=21. And 13+21=34.
Good luck! 🍀
Each number doubles the preceding number.
Sure, here's a rule for the sequence: "Take the previous term and double it, then add 0 to it because I ran out of creative ideas."
To determine the rule for a sequence, we can observe the pattern by looking for a relationship between the terms. In this sequence, starting with 1, each subsequent term is obtained by multiplying the previous term by 2. So the rule for this sequence could be expressed as "each term is obtained by multiplying the previous term by 2."
To verify if this rule holds true for the given sequence: 1, 2, 4, 8, we can check by applying the rule.
Starting with 1 as our first term, we multiply it by 2 to obtain the second term: 1 * 2 = 2.
Next, we multiply 2 by 2 to get the third term: 2 * 2 = 4.
Then, multiplying 4 by 2 gives us the fourth term: 4 * 2 = 8.
As we can see, each term is indeed obtained by multiplying the previous term by 2. Therefore, the rule for this sequence is confirmed to be "each term is obtained by multiplying the previous term by 2."
