It diverges; it does not have a sum.  the sum of a geometric series is given by a /(1-r) where a is the first term and the r is the ratio between the terms. r=3 in the series you have given . The absolute value of r must be less then 1 for a geometric series to converge.
        
                    
             
        
        
        
According to the law of sines:

Using the given values, we can find the angle B and find the number of possible triangles that can be formed.

The range of sin is from -1 to 1. The above expression does not yield any possible value of B, as sin of no angle can be equal to 1.45.
Therefore, we can conclude that no triangle exists with the given conditions.

Answer:
3 1/4 + 2 1/3 = 67 / 12 = 57 1/2
Step-by-step explanation:
Conversion a mixed number to a improper fraction: 3 1/4 = 3 · 4 + 1
4
 = 13
4
Conversion a mixed number to a improper fraction: 2 1/3 = 2 · 3 + 1
3
 = 7
3
Add: 13
4
 + 7
3
 = 13 · 3
4 · 3
 + 7 · 4
3 · 4
 = 39
12
 + 28
12
 = 39 + 28
12
 = 67
