write an explicit formula for a geometric sequence with a3 = 3 and a7 = 48. select all that apply.
an = 3(2)n
an = 3(2)n – 3
an = 3(–2)n
an = 3(–2)n – 3

step-by-step explanation:

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
