The first five terms of a sequence are: 4, 20, 100, 500, 2500, …

Write an explicit function to model the value of the nth term in the sequence such that f(1) = 4.

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

2

x=5
