Which answer is the explicit rule for the sequence 3, 8, 13, 18, 23 ?
an=−2+3n
an=−2+5n
an=−2−5n
an=2+5n

B.

Step-by-step explanation:

We have been given a sequence. We are asked to find the explicit rule for the given sequence.

3, 8, 13, 18, 23 ...

We know that explicit formula for a sequence is , where,

= nth term of the sequence,

= 1st term of the sequence,

= common difference.

Upon looking at our given sequence we can see that .

Let us find common difference between two terms by subtracting 3 from 8 as:

Upon substituting these values in explicit formula we will get,

Therefore, option B is the correct choice.
