Answer:
= 1
Showing Work:
1/4 ≤ 5/8 ≤ 3/4 so round it to 1/2.
1/4 ≤ 2/5 ≤ 3/4 so round it to 1/2.
Estimating:
1/2 + 1/2 = 1
Answer:
Step-by-step explanation:
we have the sequence
we know that
In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant and this term is called a common difference
Let
we know that
----> 
----> 
The common difference is 2
This is an arithmetic sequence
The general formula for an arithmetic sequence is
where
d is the common difference
n is the number of terms
substitute the given values
