5. C (Third choice)
6. 13 (Answer choice not visible)
<h3>
Answer: 18</h3>
Reason:
Subtract any pair of adjacent terms
- d = term2 - term1 = -74 - (-92) = -74+92 = 18
- d = term3 - term2 = -56- (-74) = -56+74= 18
- d = term4 - term3 = -38- (-56) = -38+56= 18
- d = term5 - term4 = -20- (-38) = -20+38= 18
Each time we get the same value to confirm that we have an arithmetic sequence of common difference 18.
Let's denote Cindy's age which is unknown with X
We know that Cindy's age is 3 times her age 6 years ago.
6 years ago Cindy's age was the present age (X) - 6 : X-6
The fact that the present age is 3 times her age 6 year ago can be written as:
3*(X-6)
So, finally:
X=3*(X-6)
