1. Which explicit formula represents an arithmetic sequence with a first term of 19 and a common difference of 4?

Option (2)

Step-by-step explanation:

If the first term of an arithmetic sequence is 'a' and common difference as 'd',

Explicit formula representing the nth term of the sequence is given by,

Here, n = number of term

If first term 'a' = 19 and common difference 'd' = 4

Explicit formula for the sequence will be,

Therefore, Option (2) will be the correct option.

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
