Determine the 5th term in the geometric sequence whose first 4 and whose common ratio is 3

324

The values in a geometric sequence are calculated by multiplying the preceding term by a "common ratio". For example, with a geometric sequence with a common ratio of 2 and the first value of 1, the sequence would be 1, 2, 4, 8, 16, and so on. Each value after the first one is multiplied by the value prior and 2. 2 * 2 = 4, 4 * 2 = 8, and so on.

For your question, the first value is 4 and the common ratio is 3. Multiply 4 by 3 to get the second value: 12. 12 times 3 is 36. 36 times 3 is 108, and finally, 108 times 3 is 324. The fifth term is 324.

4, 12, 36, 108, 324.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
