What expression can be used to find the nth term in the sequence 5,7,9, 11,...? 2n - 3

n + 2

n - 3

2n + 3

The required expression which can be used to find the nth term in the sequence is:

Hence, the fourth option i.e. 2n+3 is the correct option.

Step-by-step explanation:

Given the sequence

5, 7, 9, 11,...

An arithmetic sequence has a constant difference 'd' and is defined by  

computing the differences of all the adjacent terms

The difference between all the adjacent terms is the same and equal to

d = 2

So

Thus, the nth term of the sequence is

substitute a₁ = 5 and d = 2 in the sequence

Therefore, the required expression which can be used to find the nth term in the sequence is:

Hence, the fourth option i.e. 2n+3 is the correct option.
