Question

How do you write the first six terms of the sequence `a_n=2n`?

Answer 1

2; 4; 6; 8; 10; 12

Explanation:

substitute n= 1 for first term
n=2 for the second term, etc

Answer 2

`2,4,6,8,10,12`

Explanation:

The `color(blue)"nth term formula"`

`a_n=2n` allows us to generate any term in the sequence by substituting the appropriate value for n.

To generate the first 6 terms let n=1, 2, 3, 4, 5 and 6.

First term: `a_1=(2xx1)=2`

Second term: `a_2=(2xx2)=4`

Third term: `a_3=(2xx3)=6`

The remaining 3 terms are generated in the same way.
