Required
Determine the true statement about b
The question is incomplete as options are not given. However, a general explanation is as follows:
Rewrite 

When a = 0

When a = 1

This means that:
For 
Then 
<em>This means that: b is a number between 0 and 8</em>
The correct answer should be c) 3.
Answer:
I got 22.4
Step-by-step explanation:
I used the formula A=1/2bh
A=1/2(8)5.6
A=4(5.6)
A=22.4
Step-by-step explanation:
The above sequence is a geometric sequence
For an nth term in a geometric sequence

where
n is the number of terms
a is the first term
r is the common ratio
From the question
a = 5
r = 10/5 = 2
Therefore the explicit formula for this sequence is
