Math Problem Statement
Here is a sequence with a two-step term-to-term rule. What is the next term in the sequence? Start at 6. Multiply by 3 then add 2 each time.
Solution
Let's analyze the problem.
Sequence Rule:
- Start at 6.
- Multiply by 3 and then add 2 each time.
Step-by-step Calculation:
-
The first term is given as 6.
-
To find the second term:
- ,
- .
So, the second term is 20.
-
To find the third term (next term after 20):
- ,
- .
Answer:
The next term in the sequence is 62.
Would you like a detailed explanation of sequences or rules like this?
Here are 5 related questions to deepen your understanding:
- What happens if we reverse the operation (subtract 2 and divide by 3) to find earlier terms?
- How would the sequence change if we added a third operation (e.g., divide by 2)?
- Can you write the nth term of this sequence as a formula?
- How would the pattern change if we started with a different initial term?
- Could you identify a similar sequence that grows slower (e.g., multiply by 2 instead)?
Tip: When working with sequences, always test your rule on at least the first two terms to verify its accuracy.
