Question

What is the third term of the sequence? a1 = m an = 2an-1

Answer 1

hello :
if n = 3
a3 =2a2
a2 = 2m
a3 =4m

Answer 2

Answer: Our third term is 4m.

Explanation:

Since we have given that

`a_1=m\\\\a_n=2a_(n-1)`

We need to find the third term i.e.
`a_3`

According to general recursive terms:

`a_3=2a_2`

So, we first find the second term:

`a_2=2a_1\\\\a_2=2m`

so, our third term becomes,

`a_3=2a_2\\\\a_3=2* 2m\\\\a_3=4m`

Hence, our third term is 4m.
