What’s the question though lol
No it not correct because you had forgot to divide +5 form -2 and that will give you it will be 2.5 but in fraction form it will be -2 1/2
Step-by-step explanation:
The common ratio is: r=0.3333333333333333
The sum of this series is: s_4=4320
The general form of this series is: a_n=2916*0.3333333333333333^(n-1)
So you do 180-45 then you put the 2k and k together and get 3k. Then after you get 135 (by doing 180-45) and divide that by 3 which is 45
