The first term is 896.
The common ratio is -448/896 = -1/2.
The formula tells you the n-th term (an) is
.. an = a1*r^(n-1)
As with any formula, you substitute the given values to find the one you want to know.
.. a8 = 896*(-1/2)^(8 -1) = -896/128 = -7
Even if you don't know how to do the arithmetic, your calculator does.
The eighth term of the sequence is -7.
