n = 8
the sum to n terms of a geometric sequence is
=
where a is the first term and r the common ratio
here a = 16 and r = = = - 2
= ( 16( 1 - ( - 2 )^n )/1 - (- 2 )) = - 1360
( 1 - (- 2 )^n ) = - 1360
multiply both sides by
1 - (- 2 )^n = - 255
- (- 2 )^n = - 256
)-2)^n = 256
note that and = 256
hence n = 8

Answer:
a. $1,617
b. $4,983
Step-by-step explanation:
a. The account suffered a decrease of 24.5% of the original sum of $6,600.
This amount in cash is:
= 24.5% * 6,600
= $1,617
b. If the account reduced by $1,617, the balance left is:
= 6,600 - 1,617
= $4,983
