3 Each term is divided by 3 to produce the following term.

Consecutive terms in the sequence are being divided by -2. Therefore, -1 / -2 = 1/2 or 0.5.

The next number is 25 but there are the sequence is infinite so there can be no end to the sequence.

44. You're adding 11 then 9 each time !

The sequence indicates that one number is added to the previous number to find the value of the next number. Example 1 (+0) - 1 (+1) - 2 (+1) - 3 (+2) - 5 (+3) - 8 (+5) - 13. The next number in the sequence would be 21 (13 + 8).

No. Grapes have nothing to do with a recursive series of numbers following the rule that any number is the sum of the previous two.

The next number in the sequence is... 64

0 + 2 + 3 = 5 2 + 3 + 5 = 10 3 + 5 + 10 = 18 5 + 10 + 18 = 33

This is a Fibonacci sequence. Each number in the sequence is the sum of the previous two numbers:3+5=85+8=138+13=2113+21=34

37: How? Every time a new number is put into the sequence, when you subtract it from the number before it, it will equal an odd number of greater value. For example; 72-69=3 69-64=5 64-57=7 57-48=9 48-37=11

That mRNA sequence had to come from the complement to it. Remeber that the sequence is normally read 5' to 3'. The complement that produced it would be seen in the 3' to 5' orientation (reverse) during transcription. Therefore, find the complement source by reading the sequence in reverse and making the following substitutions: a becomes t, u becomes a, g becomes c, and c becomes g. The result is the following DNA source sequence read 5' to 3': ctaagtcgcaatttttggcat.

3.3.5.4.4.6 It seems that the sequence takes the doubled numbers than adds two to the said number, such as five. So with that theory it would be logical that six would come after the doubled fours.

No, the word follow is a verb (follow, follows, following, followed), to come after in sequence, to go after someone or something. The noun forms for the verb to follow are follower and the gerund, following.

It is impossible to say what sequence comes after the given set of numbers. What I can do is to suggest what number might come next in the given sequence.Using the ruleUn = (7n5 - 129n4 + 891n3 - 2859n2 + 4298n - 1488)/24 for n = 1, 2, 3, ...the next number is 85.

The sequence goes (starting from the six): Up 3: 6 + 3 = 9 Then you subtract 1: 9 - 1 = 8 Then you add 3 again: 8 + 3 = 11 then subtract 1 again: 11 - 1 = 10 The sequence is up 3, minus 1. You subtract 1 from 13 to get the 12, then you have to add 3 again. 12 + 3 = 15 15 comes next. Hope I helped! - Darg

These are square numbers of 3, 4, 5 with alternating sign, I'd expect to continue the sequence with 36, -49, 64, -81, 100

The next number is 27.5. begin by subtracting the first two then add 2 to the answer each time to come up with the next number

A sequence.

The next four number in the sequence are... 4,5,5 & 6

Any number can come next in the sequence. Given ANY number, it is possible to find a polynomial of order 7 that will generate the above numbers and the chsen extra number. And polynomials are not the only kind of functions. However, the polynomial of order 6 that will fit these data is Un = (-53n6 + 1245n5 - 11525n4 + 53355n3 - 128462n2 + 150960n - 63000)/360 for n = 1, 2, 3, ... and, accordingly, the next number in the sequence is -175.
