The pattern is you multiply by 3, and add 2, so the missing number would be 53
The answer would be 1^2.
To find this, first you divide 6 (numerator) by 6 (denominator) to get 1. Then you subratct the power of 6, from the power of 8, to get 2. Thus getting a final answer of 1^2.
I hope this helps!
A is the correct answer
when x=0, b to the 0th power is 1, f(x)=a*1=a
Y=3.4x
2*3.4=6.8
5*3.4=17
8*3.4=27.2
11*3.4=37.4
