Which formula defines the sequence \small f\left(1\right)=2, \small f\left(2\right)=6, \small f\left(3\right)=10, \small f\left(4\right)=14, \small f\left(5\right)=18? a \small f\left(1\right)=6, and \small f\left(n\right)=4+f\left(n-1\right) for \small n\ge2 b \small f\left(1\right)=2, and \small f\left(n\right)=2+f\left(n-1\right) for \small n\ge2 c \small f\left(1\right)=2, and \small f\left(n\right)=6+f\left(n-1\right) for \small n\ge2 d \small f\left(1\right)=2, and \small f\left(n\right)=4+f\left(n-1\right) for \small n\ge2

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

do your own work and don"t cheat.

step-by-step explanation:

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
