What do you get if you do the following divisions?

16.4/-14.76=
-14.76/13.284=
13.284/-11.9556=

Remember that a geometric sequence is one where each term produces the next term by multiplication by a constant.  Nothing says the constant has to be positive!

If you have a sequence $\{a_k\}, k = 1, 2, ... \text{and } a_k = a_0 r^k$. $$a_0 = 16.4$$$$r = (-14.76/16.4)$$$$a_{22} = a_0 r^{22} = $$

Looks like the ratio is supposed to be -9/10.
