Step 2: 8y-5=10+3y is wrong
And the second step is right
Answer:
The 4th term in the sequence is -8.
Step-by-step explanation:
The nth term of the sequence B is given by:
![B(n) = (-2)^{n-1}](https://tex.z-dn.net/?f=B%28n%29%20%3D%20%28-2%29%5E%7Bn-1%7D)
So the fourth term will be given by:
B when n = 4, that is, B(4).
![B(4) = (-2)^{4-1} = (-2)^{3} = -8](https://tex.z-dn.net/?f=B%284%29%20%3D%20%28-2%29%5E%7B4-1%7D%20%3D%20%28-2%29%5E%7B3%7D%20%3D%20-8)
The 4th term in the sequence is -8.
Answer:
x = 4/7
Step-by-step explanation:
x^3 = 64/ 343 // - 64/ 343
x^3 - ( 64/ 343 ) = 0
x^3 - 64 / 343 = 0
1*x^3 = 64/ 343 // : 1
x^3 = 64/ 343
x^3 = 64/ 343 // ^ 1/3
x = 4/ 7
