Math Problem Statement
a sequence starts 1/2, 1/4, 1/8,... a. Give a rule tat the sequence could follow.
Solution
The sequence you provided is:
To identify a rule that this sequence could follow, we observe that each term is half of the previous term.
Rule for the Sequence:
Each term in the sequence is obtained by multiplying the previous term by .
Alternatively, you can express this sequence using the formula for the th term:
where starts from 1.
Thus:
- And so on...
Would you like any more details or explanations?
Here are five related questions:
- What type of sequence is this, arithmetic or geometric?
- How would you find the 10th term in this sequence?
- What happens to the terms as increases indefinitely?
- Can you find the sum of the infinite series of this sequence?
- How would the rule change if the sequence started with instead of ?
Tip: This sequence is an example of a geometric sequence, where each term is obtained by multiplying the previous term by a constant factor, known as the common ratio.
