<h3>What is an addition expression?</h3>
This is a way of taking the sum of two or more expressions.
Given the following parameters
- The distance while descending = -13.7 meters
- The distance while ascending = +15.2 meters
An additional expression in the form of Descent + Ascent to represent this situation will be -13.7 + 15+ 2
<u>Calculate the sum:</u>
Sum = -13.7 + 15+ 2Sum = 3.3 meters
Hence the sum means that Eric is 3.3 m above sea level.

Answer:
36
Step-by-step explanation:
The numbers given represent an arithmetic series with a common difference of -5. The formula to find the nth term of an arithmetic sequence is:
a + (n - 1)d
where a is the first term and d is the common difference. We can substitute our values in:
261 + (46 - 1)(-5)
261 + (45)(-5)
261 + (-225)
36
