The third term of the sequence equals . Now consider the fourth term: it is the sum of the first three terms. However, as the first two terms sum to the third term, the sum of the first three terms is twice the third term, i.e. . So the fourth term is twice the third term. ...

Terms of a Sequence:If a sequence follows a particular term in every term, then we can find its general term on the form of a variable n. This general term helps us to find every term of the sequence. As, for the given sequence, its general term is given here. So, to ...
