Answer:
f(n)=2X6ⁿ⁻¹
Step-by-step explanation:
a₁=2
aₙ=6aₙ₋₁ for n≥2
a₂=6a₂₋₁=6a₁=6*2=12
a₃=6a₃₋₁=6a₂=6*12=72
a₄=6a₄₋₁=6a₃=6*72=432
This is a geometric sequence with:
First term, a=2
Common ratio, r= 12/2=6
For a geometric sequence, the nth term is given by:
Uₙ=arⁿ⁻¹
Uₙ=2X6ⁿ⁻¹
Therefore, the explicit formula for the sequence f(n) is given as:
f(n)=2X6ⁿ⁻¹

Step-by-step explanation:
if its the plus?
15/35 = y/84
to find what value of y makes the proportion true, you actually just need to solve for y.
15/35 = y/84 ... first, multiply both sides by 84
(15*84)/35 = y
1260/35 = y
36 = y
so, these values are proportional when y = 36. you can check this by getting the decimal of both and seeing if they're equal:
(15/35) = 0.428
(36/84) = 0.428
