At n = 2
a₂ = (-1)² + 3a₂₋₁ + 2
a₂ = 1 + 3a₁ + 2
a₂ = 1 + (3)(5) + 2
a₂ = 18
At n = 3
a₃ = (-1)³ + 3a₃₋₁ + 2
a₃ = -1 + 3a₂ + 2
a₃ = -1 + (3)(18) + 2
a₃ = 55
At n = 4
a₄ = (-1)⁴ + 3a₄₋₁ + 2
a₄ = 1 + 3a₃ + 2
a₄ = 1 + (3)(55) + 2
a₄ = 168
The first four terms are 5, 18, 55, 168
The answer is 80 you divide 240.00 into 3 and get 80
Answer:
58 + 60
Step-by-step explanation:
Even integers are always seperated by 2.
Answer:
Part A: 2 - 10
The 5 is the width in metres, the x is the extension in metres, and the 8 is the length in metres.
Step-by-step explanation:
5(x + 8) Distribute the properties first. (5)x +8(5)
Then multiply them. 5x + 40.
Next we want to isolate x, so we will subtract 40 to cancel out the +40. We do this on both sides to balance it.
5x + 40 = 0
5x + 40 - 40 = 0 - 40
5x = -40
Next we will divide by 5 to cancel out the multiply by 5.
5x/5 = -40/5
x = -8
So an equivalent expression would be anything that equals an answer of -8, such as 2 - 10.
