What is descending geometric sequence?

A geometric sequence is a sequence where each term is a constant multiple of the preceding term. This constant multiplying factor is called the common ratio and may have any real value. If the common ratio is greater than 0 but less than 1 then this produces a descending geometric sequence. EXAMPLE : Consider the sequence : 12, 6, 3, 1.5, 0.75, 0.375,...... Each term is half the preceding term. The common ratio is therefore ½ The sequence can be written 12, 12(½), 12(½)2, 12(½)3, 12(½)4, 12(½)5,.....

How do you find the nth sequence term?

First, you must find the difference between the numbers, for example if the numbers were 3, 5, 7, 9, 11 then it would be 2. All you have to do is find out the difference between 2 and the first number, which happens to be 3. So 3-2 equals 1.so the equation would be2n+1you always use n for the nth sequence term
