Write an equation for the nth term of the arithmetic sequence: 15,28,41 ....

11111nata11111 [884]

Answer:

The equation for the nth term of the given arithmetic sequence is: $\mathbf{a_n=13n+22}$

Step-by-step explanation:

We need to write an equation for the nth term of the arithmetic sequence:

15,28,41 ....

The equation for arithmetic sequence is: $a_n=a_1+(n-1)d$

Where $a_n$ is the nth term, $a_1$ is first term and d is common difference

In the given sequence we have:

a₁ = 15

a₂ = 28

We can find common difference using the formula:

$a_n=a_1+(n-1)d\\Put\: n=2, a_2=28\: and\: a_1=15\\a_2=a_1+(2-1)d\\28=15+d\\d=28-15\\d=13$

So, the common difference d is 13

Now, equation for nth term will be:

$a_n=a_1+(n-1)d\\Put\:a_1=15, d=13\\a_n=15+(n-1)13\\Solving:\\a_n=15+13n-13\\a_n=13n+2$

So, the equation for the nth term of the given arithmetic sequence is: $\mathbf{a_n=13n+22}$

where n=1,2,3..

What is the equation for the hyperbola shown?

castortr0y [4]

Answer:

$\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1$

Step-by-step explanation:

Since the hyperbola opens left and right with a center at the origin, then

$\frac{x^{2} }{^{2} } - \frac{y^{2} }{b^{2} } = 1$

In the graph a = 60 and b = 11

$\frac{x^{2} }{60^{2} } - \frac{y^{2} }{11^{2} } = 1$ .

$\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1$
