Write an equation for the nth term of the arithmetic sequence. Then find a50.
julia-pushkina [17]

Step-by-step explanation:

Since the sequence above is an arithmetic sequence

For an nth term in an arithmetic sequence

A(n) = a + ( n - 1)d

where a is the first term

n is the number of terms

d is the common difference

From the question

a = 1/3

d = 1/2 - 1/3 = 1/6 or 2/3 - 1/2 = 1/6

Substitute the values into the above formula

That's

<h3>A(n) =  \frac{1}{3}  + (n - 1) \frac{1}{6}  \\  =  \frac{1}{ 3}  -  \frac{1}{6}   +  \frac{1}{6} n</h3>

So the nth term of the sequence is

<h3>A(n) =  \frac{1}{6}  +  \frac{1}{6}n</h3>

For a50 since we are finding the 50th term

n = 50

So we have

<h3>A(50) =  \frac{1}{6}  +  \frac{1}{6} (50) \\  =  \frac{1}{6}  +  \frac{25}{3}</h3>

We have the final answer as

<h3>A(50) =  \frac{17}{2}</h3>

Hope this helps you

Identify examples and non-examples of the standard form of a linear function.
marin [14]

Answer:

  1. 5x - 3y = 9 (Example)
  2. y = 1/2x - 3 (Non-Example)
  3. 2x + 3y = 0 (Example)
  4. x + y = 1 (Example)
  5. x = 6y (Non-Example)
  6. y = x - 2 (Non-example)

Step-by-step explanation:

Standard form of the equation is given by:

Ax + By = C

Where

  • x and y are variables
  • A, B and C are constants which must be Integers. A should always be positive.

Considering the definition, we can identify the examples and non-examples of standard from of a linear equation.

<h3>5x - 3y = 9</h3>
  • In a form of Ax + By = C
  • A,B and C are constants
  • A=5 is positive

It is an EXAMPLE of standard form of linear function

<h3></h3><h3>y = 1/2x - 3</h3>
  • Not in the form of Ax + By =C

NON-EXAMPLE

<h3></h3><h3>2x + 3y = 0</h3>
  • In a form of Ax + By = C
  • A,B and C are constants
  • A=5 is positive

It is an EXAMPLE of standard form of linear function

<h3></h3><h3>x + y = 1</h3>
  • In a form of Ax + By = C
  • A,B and C are constants
  • A=5 is positive

It is an EXAMPLE of standard form of linear function

<h3></h3><h3>x = 6y</h3>
  • Not in the form of Ax + By =C

NON-EXAMPLE

<h3></h3><h3>y = x - 2</h3>
  • Not in the form of Ax + By =C

NON-EXAMPLE
