-5

The numbers could be from the sequence with a(1) = -3 and the common ratio r = (-2)If so, thena(7) = -3*(-2)^6 = -3*64 = -192.Of course, it is entirely possible that the numbers do not form a geometric sequence but a polynomial sequence such asa(n) = (27*n^3 - 189*n^2 + 396*n - 240)/2 and if so, a(7) = 1266.

It is: -3072

No. Any number with a terminating or repeating decimal expansion is rational."Rational" in numbers means that it can be expressed as a ratio of integers (i.e. a fraction) .... in this case, -12/5.

Because 3 * 2 = 6, 6 * 2 = 12, and 12 * 2 = 24, the common ration of the sequence is 2. If we are given the fact that the sequence does have a common ratio, the answer can be found by simply taking 6/3 = 2.

No, geometric, common ratio 2

Yes, that's what a geometric sequence is about.

26:24 = 13:12 Simplify them using a common multiple.

ratio: 24% : 22% = 12 : 11

ratio : 22% : 24% = 11 : 12

The ratio 6:12 can be simplified down to 3:6, and then lastly 1:2. In the ratio 13:24, it is as simplified as we can make it. Thus 13:24 > 6:12.

If the first term is 12 and the seventh term is 36, then we have gone up 36-12 in the space of 6 term changes. This is 24 per 6 changes, which can be written as the division 24/6. This works out as 4. Thus the common difference in the sequence is 4.

12:1

The ratio is 9:12 (girls:boys)Simplified the ratio is 3:4 When there are 24 girls, there will be 32 boys. (3:4 = 24:32)

The least common multiple of 24 , 8 , 12 = 24
