Answer:

#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.
