The first terms of an infinite geometric sequence, un are 2, 6, 18, the first terms of a second infinite geometric sequence, vn are 2, -6, 18, - the terms of a third sequence wn are defined as wn = un + vn

1. the finite series, summation: upper limit= 225, lower limit k=1, formula wk
can also be written in the form summation: upper limit= m, lower limit k=0, formula 4r^k.
find the value of r.

2. find the value of m

r = 9 and m = 112

Step-by-step explanation:

Write W in terms of U and V.

Define U and V using geometric series formula.

Use sum of geometric series formula.

Simplify.

Therefore, r = 9 and m = 112.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
