Neither.

It could be polynomial (of order 4 or more) or something else.

Is 3 6 12 24 48 an arithmetic sequence?

No, geometric, common ratio 2


Is the sequence 3 5 7 9 geometric or arithmetic or neither?

It is arithmetic because it is going up by adding 2 to each number.


What is the geometric mean and the arithmetic mean of 7 x sqrt3 and 21 x sqrt3?

The arithmetic mean is simply (7+21)sqrt(3)/2 = 14sqrt(3) = 24.25 (to 2 d.p.) The geometric mean is sqrt [ 7sqrt(3) x 21sqrt(3) ] = sqrt [ 7 x 21 x 3 ] = sqrt [21 x 21] = 21


What describes the sequence 1 1 2 3 5 is it arithmetic or geometric?

It is an arithmetic sequence. To differentiate arithmetic from geometric sequences, take any three numbers within the sequence. If the middle number is the average of the two on either side then it is an arithmetic sequence. If the middle number squared is the product of the two on either side then it is a geometric sequence. The sequence 0, 1, 1, 2, 3, 5, 8 and so on is the Fibonacci series, which is an arithmetic sequence, where the next number in the series is the sum of the previous two numbers. Thus F(n) = F(n-1) + F(n-2). Note that the Fibonacci sequence always begins with the two numbers 0 and 1, never 1 and 1.


Is the sequence 2 3 5 8 12 arithmetic or geometric?

The sequence 2, 3, 5, 8, 12 is neither arithmetic nor geometric. In an arithmetic sequence, the difference between consecutive terms is constant, while in a geometric sequence, the ratio between consecutive terms is constant. In this sequence, there is no constant difference or ratio between consecutive terms, so it does not fit the criteria for either type of sequence.
