The interest rate would be 5%
<span>1st term:: a/r = (-1/5)/(2) = -1/10
2nd term:: a = -1/5 = -2/10
3rd term:: a*r = (-2/10)(2) = -4/10</span>
Answer:
The number is 162.
Step-by-step explanation:
Let's let the number =n
So, we can set up an equation.
(n/9) is a number divided by 9.
Its "quotient" (the answer to that expression) is multiplied by 6.
6(n/9)
The product (answer) is 108.
6(n/9) = 108.
Then we can solve.
6(n/9) = 108
(n/9) = 18
n = 162
