Answer:positive
Step-by-step explanation:
(24/2){2(152) + (24-1)(-14)} = -216. -216 is the sum of the sequence.
N= 1
1(1-1)-4 = 0-4 = -4
n=2
2(2-1)-4= 2-4= -2
n=3
3(3-1)-4= 6-4= 2
n=4
4(4-1)-4= 12-4= 8
Answer:
Simplifying
4x + -3y = 20
Solving
4x + -3y = 20
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
4x + -3y + 3y = 20 + 3y
Combine like terms: -3y + 3y = 0
4x + 0 = 20 + 3y
4x = 20 + 3y
Divide each side by '4'.
x = 5 + 0.75y
Simplifying
x = 5 + 0.75y
God bless you & have a beautiful rest of your Day or Night!
