What are the first 5 terms of the sequence if; an=2(an-1+an-2), a1=-2, a2=-3? ? a. –3, –2, –10, –24, –68 b. –3, –2, –4, –8, –16 c. –2, –3, –10, –26, –72 d. –2, –3, –5, –8, –13

answer: 800

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
