First, we inspect what type of sequence is the order of the coordinates:
a2 = 1
a3 = 2
a4 = 4
Getting the difference,
a3 - a2 = 1
a4 - a3 = 2
The differences are not equal; hence, the sequence is not arithmetic.
Getting the ratio:
a3/a2 = 2
a4/a3 = 2
The common ratio is 2. Using the general form for a geometric series:
an = a1 r^(n-1)
If n = 2
1 = a1 (2)^(2-1)
a1 = 1/2
So,
an = (1/2) (2)^(n-1)
The answer is the first option.
Who is jared and ur options are??
Answer:
3/12
Step-by-step explanation:
OR:
14 is equivalent to 3/12 because 1 x 12 is the same as 4 x 3. They both equal 12. 28 is equivalent to 3/12 because 2 x 12 is the same as 8 x 3. They both equal 24.
