Answer:
x = 5/2
Step-by-step explanation:
2^x+4 = 2^3x-1
x + 4 = 3x - 1
3x - x = 4 + 1
2x = 5
x = 5/2
Im not sure but I think could be
3x=0
Divide 4 to both sides of the equation
Answer:
4.5, -27, 162,-972, 5832
Step-by-step explanation:
The given recursive definition is,

This will form a geometric sequence with first term 4.5 and common ratio r=-6.
When n=2, we have:

When n=3, we get:

When n=4, we get:

When n=5, we get:

Therefore the first five terms are:
4.5, -27, 162,-972, 5832
