Write an equation for the nth term of the arithmetic sequence. Then find a40.

Olegator [25]

Answer:

The nth term is: $a_n = \frac{1}{4} + \frac{1}{4}(n-1)$

a40 = 10

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms is always the same, and this difference is called common difference.

The nth term of a sequence is given by:

$a_n = a_1 + (n-1)d$

In which $a_1$ is the first term and d is the common difference.

1/4,1/2

This means that:

$d = \frac{1}{2} - \frac{1}{4} = \frac{2}{4} - \frac{1}{4} = \frac{1}{4}$

1/4

This means that $a_1 = \frac{1}{4}$

The nth term is:

$a_n = a_1 + (n-1)d$

$a_n = \frac{1}{4} + \frac{1}{4}(n-1)$

Then find a40.

$a_{40} = \frac{1}{4} + \frac{1}{4}(40-1) = \frac{1}{4} + \frac{39}{4} = \frac{40}{4} = 10$

a40 = 10

The lines given by the equations y=4x and y=0.25x are

d1i1m1o1n [39]

They are not parallel because the slopes are different (slope of 4 and slope of 0.25)

Neither are they perpendicular. If they were then m1*m2 ( the product of their slopes) would be -1 ). The product of these slopes = 4*0.25 = 1)

So choice A is the correct one.
