Answer:
b(1) = 2 , b(2) = 3 , b(3) = 5 , b(4) = 9 , b(5) = 17
Explanation:
In the sequence we are shown that the next term is equal to 2 times n-1 (the previous term) minus one.
Thus, to find term 2 in the sequence we must multiply it by term 1 (we are given that it is 2) and then subtract 1.
2(2) - 1 = 3
We keep doing this until we get the first 5 terms in the sequence.
3(2) - 1 =5
5(2) - 1 =9
9(2) - 1 = 17
