find the 10th term of the sequence Tn=2n-5
Answers
Answer:
15
Step-by-step explanation:
Tn=2n-5
T10=2(10)-5
=20-5
=15
the 10th term of the sequence is 15.
The given sequence is Tn = 2n - 5, which means that the first term of the sequence is T1 = 2(1) - 5 = -3. To find the 10th term of the sequence, we simply need to plug in n = 10 into the formula for Tn.
T10 = 2(10) - 5
T10 = 20 - 5
T10 = 15
Therefore, the 10th term of the sequence is 15.
The formula for Tn = 2n - 5 is an example of an arithmetic sequence, where each term is found by adding a constant difference to the previous term. In this case, the constant difference is 2.
By understanding this pattern, we can easily find any term of the sequence by plugging in the appropriate value for n.
