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.
