Answer: Our third term is 4m.

Step-by-step explanation:

Since we have given that

[tex]a_1=m\\\\a_n=2a_{n-1}[/tex]

We need to find the third term i.e. [tex]a_3[/tex]

According to general recursive terms:

[tex]a_3=2a_2[/tex]

So, we first find the second term:

[tex]a_2=2a_1\\\\a_2=2m[/tex]

so, our third term becomes,

[tex]a_3=2a_2\\\\a_3=2\times 2m\\\\a_3=4m[/tex]

Hence, our third term is 4m.
