Question:
What is the common ratio between successive terms in the sequence?
27, 9, 3, 1
Answer:
common ratio =
Step-by-step explanation:
In a geometric progression, the common ratio, r, is the ratio of a term in the sequence to a preceding term in that same sequence. In other words, the common ratio is found by dividing a term by the term just before it. For example, if the geometric sequence is:
a, b, c, d...
The common ratio is found by any of the following;
r = ----------(i)
r = -----------(ii)
r = ------------(iii)
Any of equations (i) through (iii) will give the common ratio of the sequence.
============================================================
Now, from the question, the given sequence is;
27, 9, 3, 1
To get the common ratio, just divide the second term (9) by the first term (27) i.e
r = =
OR
You can also divide the third term (3) by the second term (9). i.e
r = =
OR
You can choose to divide the fourth term (1) by the third term (3). i.e
r =
Which ever adjacent terms you choose gives you the same result. Therefore, the common ratio of the given sequence is

46. We have to make the odd assumption the grocer sells for his cost, but let's not beat up the question too hard.
Again, two unknowns, <em>b</em> kilograms of Brazil nuts and <em>c</em> kilograms of cashews.
<em>... sold 12 kg of the mixture ...</em>
<em>... cashews $8/kg and Brazil nuts $10/kg and the results is $8.50/kg ...</em>
This one's a bit more involved to translate because we have to recognize the total price is the 8.50 per kg times 12 kg.
The solving is pretty much just like the last one; we eliminate the unknown we're not asked for.
Answer: 9
Check: (9(8)+10(3))/12=102/12 = 8.50 good
