Let's start with an easy one: 1, 2, 3, 4, 5, ?.
2, 4, 6, 8, 10,... A(7)?.
38, 35, 32, 29, 26, ..., A(8).
49, 39, 30, 22, 15,... next term?.
3, 5, 9, 17, 33, ... next term?.
A sequence follows the rule A(n) = A(n-1)*2 + 2 // A(1) =1 // A(4) would be... 5 10 22 45.
A sequence follows the rule A(n) = A(n-2)*2 // A(1) =1 and A(2)= 3 // A(5) would be... 2 6 5 4.
In a sequence, a term in the sum of the two previous term, A(1)=1 and A(2)=2, which is the value for A(5)?.
In a sequence A(n) = n^2, Value for A(9)?.
In a sequence A(n) = (n+1)*2, value for A(5)?.
