Answer:
a1 = 24
an = an-1 × 1/2, n >1
Step-by-step explanation:
a geometric sequence is a sequence where we multiply every previous term by a certain factor to create the next term.
so, we multiply 24 by something to get 12.
and then 12 by the same something to get 6.
and then 6 by the and something to get 3.
do you see the pattern ? hmmm ?
right, we always divide by 2 (or multiply by 1/2).
the starting value a1 = 24
so,
an = an-1 × 1/2, n>1
or
n>1
Answer:
A: x = 0
B: x = All real numbers
Step-by-step explanation:
A.
Any number to the power of (0) equals one. This applies true for the given situation; one is given an expression which is as follows;
Simplifying that will result in;
As stated above, any number to the power of (0) equals (1), thus (x) must equal (0) for this equation to hold true.
B.
As stated in part (A), any number to the power (0) equals (1). Therefore, when given the following expression;
One can simplify that;
However, (1) to any degree still equals (1). Thus, (x) can be any value, and the equation will still hold true.
