Need to get these problems checked--
21. Suppose inflation of money is at a rate of 3% per year in the US. How much will a $1 candy bar cost in 30 years?
1.03^30 * 1= $2.43
22. Find the next 3 terms of the geometric sequence 4, 10, 25.
125, 625, 3125? ..Not sure about this.
23. Find the next 2 terms of the geometric sequence 50, 40, 32
128, 512? ..Not sure about this either
24. What is the eighth term of the geometric sequence whose first three terms are 3, 6, and 12?
3 * 2^7 = 384?
28. True or False: Linear and exponential functions are exactly alike.
False.
30. What is the y-intercept of the graph of y = 4^x-2?
-2?
Thanks

22. the common ratio is 10/4 or 2.5
then 25(2.5) = 62.5
62.5(2.5) = 156.25
156.25(2.5) = .... etc
23. done the same way, find the common ratio 40/50 or 4/5 or .8
the rest are correct
