Write the explicit formula for the geometric sequence.

2, 8, 32, 128, ...

A)
an = 2n-1

B)
an = 2 · 6n-1

C)
an = 2 · 2n-1

D)
an = 2 · 4n-1

Uₙ = 2(4)ⁿ⁻¹

Step-by-step explanation:

General Formula: Uₙ = a(r)ⁿ⁻¹

a = first term = 2

r = common ratio

r = (Uₙ₊₁)/Uₙ:

r = U₂/U₁

r = 8/2 = 4

∴ formula is: Uₙ = 2(4)ⁿ⁻¹

step-by-step explanation:

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
