Answer:

a_{3} = 4m).

Step-by-step explanation:

Given  : a_{1} = m and a_{n} = 2 a_{n-1}.

To find : What is the third term of the sequence.

Solution : We have given

a_{1} = m

a_{n} = 2 a_{n-1}.

For  n =2 .

a_{2} = 2 a_{2-1}.

a_{2} = 2 a_{1}.

plug  a_{1} = m

a_{2} = 2m.

For n = 3 .

a_{3} = 2 a_{3-1}.

a_{3} = 2 a_{2}.

Plug a_{2} = 2m.

a_{3} = 2( 2m).

a_{3} = 4m).

Therefore, a_{3} = 4m).
