(85 + 75) * t = 448
160t = 448
t = 448/160
t = 2.8 hrs
Answer: 2.8 hrs
Answer:
its B
Step-by-step explanation:
The recursive formula for given sequence is: 
And the terms will be expressed as:

Step-by-step explanation:
First of all, we have to determine if the given sequence is arithmetic sequence or geometric. For that purpose, we calculate the common difference and common ratio
Given sequence is:
11,4,-3,-10,-17...
Here

As the common difference is same, given sequence is an arithmetic sequence.
A recursive formula is a formula that is used to generate the next term of the sequence using the previous term and common difference
So, the recursive formula for an arithmetic sequence is given by:

Hence,
The recursive formula for given sequence is: 
And the terms will be expressed as:
