The first term of a geometric sequence is  −2100 . The common ratio of the sequence is  −0.1 .

\(g_n=g_1*r^{n-1}\) Use this formula, where r is the common ration, \(g_1\) is the first term and n is the number of term we are trying to find

\(g_7=-2100*(-0.1)^{7-1}\)

\(g_7=-2100*(0.000001)\)

\(g_7=-0.0021\)
