The <em>missing</em> pattern behind the sequence 7, 11, 2, 18, -7 is described by the formula , equivalent to the <em>recurrence</em> formula .
<h3>What is the missing element in a sequence?</h3>
A sequence is a set of elements which observes at least a <em>defined</em> rule. In this question we see a sequence which follows this rule:
(1)
Now we prove that given expression contains the pattern:
n = 0
7
n = 1
7 + (- 1)² · 2² = 7 + 4 = 11
n = 2
7 + (- 1)² · 2² + (- 1)³ · 3² = 11 - 9 = 2
n = 3
7 + (- 1)² · 2² + (- 1)³ · 3² + (- 1)⁴ · 4² = 2 + 16 = 18
n = 4
7 + (- 1)² · 2² + (- 1)³ · 3² + (- 1)⁴ · 4² + (- 1)⁵ · 5² = 18 - 25 = - 7
The <em>missing</em> pattern behind the sequence 7, 11, 2, 18, -7 is described by the formula , equivalent to the <em>recurrence</em> formula .

Can you explain this better I don’t understand
If there is 15% increase, then the value is 1.15
If there is 15% decrease, then the decimal value is .85
We want the increase a number, so we're gonna use 1.15
Let "N" be the number
To decrease or increase, we have to multiply a number by a value
1.15*N = 60
Divide both side by 1.15, you will be left with N
N =
= 52.17 (rounded to hundredth place)
Answer:
d
Step-by-step explanation:
because
12xy³z⁶/4x⁵yz¹²=3y²/x⁴z⁶
Answer:
Step-by-step explanation:
we know that
The quadratic equation in standard form is equal to
In this problem we have
the vertex is equal to the point
The zeros of the function are the points and
The graph of the figure is a vertical parabola open upward
the equation of a vertical parabola in vertex form is equal to
where (h,k) is the vertex of the parabola
substitute
with the point find the value of a
the equation in vertex form is equal to
Convert to standard form
equate to zero
