Practice over Geometric Sequences - writing the rules and finding the nth term.
1

Determine whether the sequence is geometry. If yes, identify the common ratio and give the next three terms.
{-2, 10, -50, 250,...}

Use the informative give to find the indicated value.
a5 = -68 and r = -0.5; find a1

1

Use the information given to find the indicated value. HINT: Plug in the information you have to find "r" first.
a1 = 13 and a4 = 4459; find a3
