Hello there!
If Jessica uses 3 equal sizes for all three picture frames, and she only has 1/2 of a yard, one easier way that we can convert this would be that there are 0.5 = 18 inches of Ribbon.
18 ÷ 3 = 6 ... 6 × 3 = 18.
Your correct answer would be D. 6
Answer:
Step-by-step explanation:
The equation for an arithmetic sequence is
where n is the position of the number in the sequence, a1 is the first number in the sequence, and d is the difference between the numbers in the sequence.
Our first number is 2, so a1 = 2; to get from 2 to 5 we add 3, to get from 5 to 8 we add 3. That means that d = 3. Filling in the standard form of the equation:
which simplifies to
and a bit more to
(which should tell you that arithmetic sequences are lines!)
Finding the 13th number simply requires that we replace n with 13 and solve:
so
