In summary, a sequence is a list of numbers or objects that follow a specific pattern or rule. The rule for this sequence is Tn= Tn-2/Tn-1 for n>=3 with T1=20 and T2=2. T1 and T2 represent the first and second terms in the sequence, and to find the third term, T3, we substitute n=3 into the rule: T3= T3-2/T3-1 = T1/T2 = 20/2 = 10. If n is less than 3, the rule does not apply and the sequence cannot be continued.

1)A sequence is defined by Tn= Tn-2/Tn-1 for n>=3 with T1=20 and T2=2. find the 4th term.

2) The general term of a sequence is Tn=2^n-2. Find n if Tn=1/128.

What's the answer? Please help. Thanks.

well, for the first one it is quite easy

what is the 3rd term.

T3=T1/T2, right? so the 4rth term would be T4=T2/T3, right?

2) well all you need to do here is set 1/128=2^n-2 and solve for n? do you know how to do it?
 

Related to 1)A sequence is defined by Tn= Tn-2/Tn-1 for n>=3 with T1=20 and T2=2.

1. What is a sequence?

A sequence is a list of numbers or objects that follow a specific pattern or rule.

2. What is the rule for this sequence?

The rule for this sequence is Tn= Tn-2/Tn-1 for n>=3 with T1=20 and T2=2.

3. What does T1 and T2 represent in this sequence?

T1 and T2 represent the first and second terms in the sequence, respectively.

4. How do you find the third term in this sequence?

To find the third term, T3, we substitute n=3 into the rule: T3= T3-2/T3-1 = T1/T2 = 20/2 = 10.

5. What happens if n is less than 3 in this sequence?

If n is less than 3, the rule does not apply and the sequence cannot be continued.
