What are the explicit equation and domain for an arithmetic sequence with a first term of 5 and a second term of 3?

Step-by-step explanation:

The explicit equation for an arithmetic sequence is,

Where,

= nth term in the arithmetic sequence,

= 1st term in the arithmetic sequence,

d = common difference.

Here, the first term of 5 and a second term of 3. So the common difference is -2.

Putting the values,

i.e

As n neither be negative nor fraction, because it is the number of term, so all positive integers greater than 1 will be its domain.
