Problem Num : 3 Type: Mathematical Reading Topic:Sequence  Theme:None Adjustment# : 20 Difficulty: 700 level
Category	Geometric Sequence
Analysis	Just plug in. From r*n<100, if we know r value, then we can solve it for n.
Solution/Hint	(1)r*50=500 (2)r*100+r*105=2,050 Both conditions are enough to find r.

Problem Num : 4 Type: Mathematical Writing Topic:Sequence  Theme:Set Variables Adjustment# : 20 Difficulty: 700 level
Category	Geometric Sequence
Analysis	The rule: increased by same factor.
Solution/Hint	x=10*r 14.4=x*r need to find the r. 14.4=10*r^2 r^2 = 144/100. r=12/10 x=12 Discussion: 14.4 can be given as 16.9
