Too lazy to type it all
Answer:
1)
2)
Step-by-step explanation:
1) To write an Arithmetic Sequence, as an Explicit Term, is to write a general formula to find any term for this sequence following this pattern:
<em>"Write an explicit formula for each explicit formula A(n)=-1+(n-1)(-2)"</em>
This isn't quite clear. So, assuming you meant
Write an explicit formula for each term of this sequence A(n)=-1+(n-1)(-2)
As this A(n)=-1+(n-1)(-2) is already an Explicit Formula, since it is given the first term the common difference let's find some terms of this Sequence through this Explicit Formula:
2) In this Arithmetic Sequence the common difference is 8, the first term value is 4.
Then, just plug in the first term and the common difference into the explicit formula:
Let, the width = x
Length = x + 1
It is given that, 18 = 2(x+1+x)
18 = 2(2x+1)
18 = 4x + 2
4x = 18 - 2
x = 16 / 4
x = 4
& x+1 = 5
In short, Your dimensions would be: 5 × 4 Feet
Hope this helps!
