Write the sum using summation notation, assuming the suggested pattern continues. 8 - 40 + 200 - 1000 + ...

mr_godi [17]

Each successive term is -5 times the previous one, so the underlying sequence is

$a_n=-5a_{n-1}=(-5)^2a_{n-2}=(-5)^3a_{n-3}=\cdots=(-5)^{n-1}a_1=8(-5)^{n-1}$

The sum can then be written as

$8-40+200-1000+\cdots=\displaystyle\sum_{n=1}^\infty8(-5)^{n-1}$
