Answer:
Step-by-step explanation:
The numbers don’t increase by a constant amount, so this is not an arithmetic sequence.
It appears to be a <em>geometric sequence</em>.
The <em>general formula</em> for each term in a geometric sequence is
aₙ = a₁rⁿ⁻¹
===============
Calculate the value of r
You can calculate the r-value by dividing any two consecutive terms in the sequence.
rₙ = aₙ/aₙ₋₁
a₂/a₁ = 4.5/3 = 1.5
a₃/a₂ = 6.75/4.5 = 1.5
a₄/a₃ = 10.125/6.75 = 1.5
a₅/a₄ = 15.1875/10.125 = 1.5
r = 1.5
===============
Determine the formula for the nth term
a₁ = 3; r = 1.5 Substitute the values
aₙ = 3(1.5)ⁿ⁻¹ Write the equation as a function of x
A simple algebra equation!
You have to replace each x with 4, so the equation would look like this:
-4·4+1.5·4-2.5-2·4-6.5
Evaluate the terms, you get:
-16+6-2.5-8-6.5
Then you add and subtract where needed:
-10-16 = -27
And that's the final answer!
ANSWER: 27
What is the question though in A #1
Answer: 1/6 cause there is 6 sides to a cube and ur only wanting one number
There are four equations to this solution
