Answer:
aₙ = a₁ . 5⁽ⁿ⁻¹⁾
Step-by-step explanation:
The first term in the sequence is a₁ = 6.
a₂ = 30. a₃ = 150.
We see that each consecutive term is multiplies by 5 to arrive at the next term.
That is: a₂ = 30 = a₁ . 
= 6.5 = 30.
Similarly, a₃ = 150 = 6 
Generalizing this, we have:
aₙ = a₁ . 
This is called the recursive formula of the sequence.
There are 8 people who do not like reading, and 2 people who do not enjoy playing video games. There is one person who does not like reading or playing video games.
This makes 9 non readers and 3 non gamers.
Ratio is 9:3 which simplifies to 3:1
I was wondering why my previous post was deleted (I attached the same picture below).
I spent a long time drawing and labeling a diagram as well as writing out a detailed formulaic explanation.
Use Soh Cah Toa. Soh(sin) is the Opposite side divided by the Hypotenuse side so in this case 21/20. Since we need the angle here we would use the inverse of sin. Your equation is Sin(x)=Opposite/Hypotenuse=21/20=1.05
Now solve sin(x)=1.05
Re-arange into
X=sin^-1 (1.05) but since you can’t have a inverse sin of a number more than one it is inconclusive or no answer
