Jeffrey is paying 20 percent of the original retail price because there are two 40 percent off coupons. 40 plus 40 equals 80 and that is 80 percent he is NOT paying so you subtract 80 from the total percent, which is 100, and you are left with paying 20 percent.

What is the recursive formula for this geometric sequence? –4, –24, –144, –864, ...

lesya [120]

the question does not present the options, but this does not interfere with the resolution

Let

a1=-4

a2=-24

a3=-144

a4=-864

a5=?

we know that

a2/a1=-24/-4----> 6-------> a2=6*a1

a3/a2=-144/-24---> 6-----> a3=6*a2

a4/a3=-864/-144---> 6----> a4=6*a3

therefore

a5=6*a4-----> a5=6*(-864)------> a5=-5184

hence

the formula is

an=6*a(n-1)
