Answer:
See below ↓↓
Step-by-step explanation:
a₁ refers to the first term of the sequence.
That is clearly : a₁ = <u>6</u>
<u></u>
The formula for the nth term is :
- aₙ = a₁rⁿ⁻¹
- Common ratio (r) = quotient of consecutive terms
- r = -12/6 = -2
Therefore, the nth term is :
Solve for "w" by adding 15 to both sides of the equation.
5w-15=25
5w=40
Next, divide both sides by 5 to get "w" by itself.
5w=40
W=8
