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.
The ratio of 24 to 2 is 12:1. This ratio is derived by dividing both numbers by their greatest common divisor, which in this case is 2. Dividing 24 by 2 gives 12, and dividing 2 by 2 gives 1. Thus, the ratio simplifies to 12:1.
The ratio of 12 to 24 can be simplified by dividing both numbers by their greatest common factor, which is 12. So, 12 divided by 12 is 1, and 24 divided by 12 is 2. Therefore, the simplified ratio of 12 to 24 is 1:2.
26:24 = 13:12 Simplify them using a common multiple.
The ratio of 24 to 60 can be simplified by dividing both numbers by their greatest common factor, which is 12. So, 24 รท 12 = 2 and 60 รท 12 = 5. Therefore, the ratio of 24 to 60 is 2:5.
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.
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)
