Answer:
aₙ = 2*n*n - n -1
Step-by-step explanation:
a₁ = 0
a₂ = 5 = 2*2*2 -2-1 = 8-3 = 5
a₃ = 2*3*3 -3-1 = 18-4 =14
a₄ = 2*4*4 - 4-1 = 32-5 =27
......
aₙ = 2*n*n - n -1
Answer:
n must be 3
Step-by-step explanation:
The formula for the perimeter of a rectangle of length L and width W is
P = 2L + 2W. Substituting (1/2)(n - 6) for L and 2n + 5 for W, we get:
P = 60 = n - 6 + 4n + 10, or:
60 = 5n + 4, or:
15 = 5n
Then n must be 3.
