The first term of a sequence is $x_{1}=1 .$ Each succeeding term is the sum of all those that come before it: $$x_{n+1}=x_{1}+x_{2}+\cdots+x_{n}$$ Write out enough early terms of the sequence to deduce a general formula for $x_{n}$ that holds for $n \geq 2$.

The first term of a sequence is x1 = 1. Each succeeding term is the sum of all those that come before it: xn+1 = x1 + x2 + g + xn. Write out enough early terms of the sequence to deduce a general formula for xn that holds for n ≥ 2.

Each gives the first term or two of a sequence along with a recursion formula for the remaining terms. Write out the first ten terms of the sequence. $$a_{1}=2, \quad a_{2}=-1, \quad a_{n+2}=a_{n+1} / a_{n}$$
