The fifth term of a sequence is 80. Every term after the first term of the sequence is double the previous value.
Which equation represents the explicit function for f(n), where n is the term number of the
sequence?
A f(n) = 2(5)"-1
B f(n) = 5(2)»--
Cf(n) = 10(2)n-1
D f(n) = 20(2)"-1

∞ this is your sign

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
