What are the first three terms of the sequence defined by the recursive function an=an-1-(an-2-4), when a5=-2 and a6=0

BaLLatris [955]

Answer:

6, 10, 8

Step-by-step explanation:

aₙ= aₙ₋₁ - (aₙ₋₂ - 4)= aₙ₋₁ - aₙ₋₂ + 4

a₅= -2

a₆= 0

-----------

aₙ₋₂= aₙ₋₁ - aₙ + 4

a₄= a₅- a₆ + 4 = -2 - 0 + 4 = 2
a₃= a₄ - a₅ + 4 = 2 - (-2) + 4 = 8
a₂= a₃ - a₄ + 4 = 8 - 2 + 4 = 10
a₁= a₂ - a₃ + 4 = 10 - 8 + 4 = 6

The first 3 terms: 6, 10 and 8

Factor (difference of squares) the binomial 25x^2-4 and find one of its factors

Lunna [17]

Step-by-step explanation:

Hey, there!

Here,

Given that:

$= 25 {x}^{2} - 4$

we need to find factor,

As it is in a^2-b^2 form as per its factor (a+b) (a-b), keeping same formula here,

25x^2 means (5x)^2

and 4 means 2^2

Now, it would be,

$= ( {5x)}^{2} - {2}^{2}$

$= (5x + 2)(5x - 2)$

Therefore, it's factor would be (5x+2)(5x-2).

Hope it helps....

strojnjashka [21]

Add August and September for total amount of bushels:

46,100 + 8,120 = 54,220 total bushels

Divide total bushels by total acres:

54,220 / 488 = 111.1 = 111 bushels per acre
