Answer #2:
I'll say ' H ' is.
2
The next number in the sequence would be 30. The general rule is multiply by 2, then add 1. 1 x 2 = 2 2 + 1 = 3 3 x 2 = 6 6 + 1 = 7 7 x 2 = 14 14 + 1 = 15 15 x 2 = 30
1
8
Zero
its +2, +2, -1... so the next is 10
The answer is 6 / (1-5/7). 1- 5/7 = 2/7 6 / (2/7) = 6 * (7/2) = (6*7)/2 = 42/2 = 21. Simples!
If you mean 2/1 3/2 4/3 5/4 then the next 3 terms are 6/5 7/6 8/7 and the nth term is (n+1)/n
7 because 1 2 3 4 5 6 7 8 9 10 10-1 9-2 8-3 7-4 6-5
15
7, 6.
The next number is 67. The simplest polynmial rule is Un = (8n4 - 97n3 + 412n2 - 713n + 432)/6 for n = 1, 2, 3, ...
