Sorry i dont speak this language
Answer:
Step-by-step explanation:
2b^2 - 3b + 4a^2........a =-6 and b = 8
now we sub
2(8^2) - 3(8) + 4(-6^2)
2(64) - 24 + 4(36)
128 - 24 + 144
272 - 24
248 <==
It’s r=-2
Just by doing the work to it I got that answer
Nth term = a1r^(n-1)
4th term = 15* (1/3)^3 = 15/27 = 5/9
I think ur problem is missing something bc I got this
