Which of the following is the explicit rule for the sequence -3, 5, 13, 21 ... *
1 answer:
Answer:
= 8n - 11
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence, that is
5 - (- 3) = 13 - 5 = 21 - 13 = 8
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3 and d = 8 , thus
= - 3 + 8(n - 1) = - 3 + 8n - 8 = 8n - 11 ← note this is the second option, that is
f(n) = - 3 + 8(n - 1)

Answer:
The final price of blender after sale off and sales tax = $123.552 A
Step-by-step explanation:
Given as :
The costs of blender = $130
The sale off percentage = 12%
The sales tax applied on blender price = 8%
Now
The cost of blender after sale off = $130 - 12% of $130
The cost of blender after sale off = $130( )
I.e The cost of blender after sale off = $130 × = $114.4
Again, sales tax of 8% is applied after sale off
So, Final price of blender = $114.4 + 8% of $114.4
Final price of blender = $114.4 ()
I.e Final price of blender = $123.552
Hence the final price of blender after sale off and sales tax = $123.552 Answer
