Aug 24, 2016

2; 4; 6; 8; 10; 12

#### Explanation:

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

$2 , 4 , 6 , 8 , 10 , 12$

#### Explanation:

The $\textcolor{b l u e}{\text{nth term formula}}$

${a}_{n} = 2 n$ 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: ${a}_{1} = \left(2 \times 1\right) = 2$

Second term: ${a}_{2} = \left(2 \times 2\right) = 4$

Third term: ${a}_{3} = \left(2 \times 3\right) = 6$

The remaining 3 terms are generated in the same way.
