The pattern is “Next term is 2 less than the previous term”.

And next two terms are 5 and 3.

Explanation of Solution

Given:

The given sequence is,

13, 11, 9, 7, …..

Here,

  $\begin{array}{l}11-13=-2\\ 9-11=-2\\ 7-9=-2\end{array}$

So, the pattern is that the next term is 2 less than the previous term.

Now, the next two term will be

  $\begin{array}{l}7-2=5\text{and}\\ 5-2=3\end{array}$
