Given:
The sequence is 5, 15, 25, ... .
To find:
The explicit formula for the nth term of the given sequence.
Solution:
We have,
5, 15, 25, ...
It is an AP because the difference between two consecutive terms are same.
Here,
First term : a = 5
Common difference : d = 15 - 5 = 10
Now, the explicit formula for the nth term of an AP is
Where, a is the first term and d is the common difference.
Therefore, the required explicit formula for the given sequence is .

Answer:
Option B.
Step-by-step explanation:
From the picture attached, figure above the x-axis is the pre-image and below the axis is the image.
Let's choose a point B of the image having coordinates (0, 2).
When the point B is transformed, coordinates of the point B' is (0, -2)
And the rule for this transformation will be,
(x, y) → (-x, -y)
This rule shows the reflection of pre-image over the origin.
Option (B). will be the answer.
