Question

PLEASE HELP WITH ALGEBRA!!!

Answer 1

Answer: aₙ = 3 + 4ⁿ⁻¹

So the formula would be:

aₙ = 3 + 4ⁿ⁻¹

Where a₁ = 3

Common Ratio (r) = 4

And n = the term number that needs to be found out

Step-by-step explanation:

Let's check if the answer is right:

To find the 1st number in the term we can substitute 1 in for n in the equation:

a₁ = 3 + 4¹⁻¹

a₁ = 3 + 4⁰

a₁ = 3 + 1

a₁ = 4

And if going back and checking the first number in the sequence given is indeed 4, therefore this equation is correct

Hope this helps!
