PLEASE HELP PLEASE WILL GIVE BRAINLIEST !!!!! Freya is training for a track race. She starts by sprinting 200 yards. She gradual

DedPeter [7]

Answer:

A. $a_n=200+(n-1)5$

Step-by-step explanation:

Given,

The initial sprinting of Freya = 200 yards,

Also, She gradually increases her distance by 5 yards per day,

So, in second day her sprinting = 200 + 5 = 205 yards,

In third day = 205 + 5 = 210 yards,

In fourth day = 210 + 5 = 215 yards,

...................., so on,.....

Hence, the sequence that shows the given situation,

200, 205, 210, 215, .........

Which is an A.P.

That having first term, a = 200,

Common difference, d = 5,

Thus, the explicit formula for the given situation is,

$a_n=a+(n-1)d$

$\implies a_n=200+(n-1)5$

Option A is correct.

A Pythagorean triple is a triple of natural numbers satisfying the equation a^2+b^2+c^2.

Softa [21]

X, x+2 - two consecutive odd or even numbers
Add the reciprocals of these numbers.
$\frac{1}{x}+\frac{1}{x+2}=\frac{x+2}{x(x+2)}+\frac{x}{x(x+2)}=\frac{x+2+x}{x^2+2x}=\frac{2x+2}{x^2+2x}
$

Now add the squares of the numerator and denominator, as in the example.
$(2x+2)^2+(x^2+2x)^2= \\ 4x^2+8x+4+x^4+4x^3+4x^2= \\ x^4+4x^3+8x^2+8x+4$

So this number has to be a perfect square.
$x^4+4x^3+8x^2+8x+4= \\
x^4+2x^3+2x^2+2x^3+4x^2+4x+2x^2+4x+4= \\
x^2(x^2+2x+2)+2x(x^2+2x+2)+2(x^2+2x+2)= \\
(x^2+2x+2)(x^2+2x+2)= \\
(x^2+2x+2)^2$
It is a perfect square, so this method always works.

The numbers $2x+2, \ x^2+2x, \ (x^2+2x+2)^2$ are a Pythagorean triple for any $x \in \mathbb{N^+}$ .
