The first term of a geometric sequence is -3 and the common ratio is 2. Find the 8th term.

Hello, [latex] u_{1} =-3\\ u_{2} =-3*2=-6\\ u_{3} =-3*2^2=-3*4=-12\\ ...\\ u_{8} =-3*2^7=-3*128=-384\\ [/latex]

nth term for  a geometric sequence; nth=[latex] ar^{n-1} [/latex] where a is the first term, r the common ratio and n the position of the term; a=-3 r=2 8th term=(-3)*[latex] 2^{7} [/latex] 8th term=-384
