What are the first five terms of a= 2 × n
​

2,4,6,8,10

Step-by-step explanation:

To find the first 5 terms we can substitute numbers for "n"

We can create a table:

x              y

1              2

2             4

3             6

4             8

5            10

To get the values we just plug in numbers:

a(1)=2(n)

a(1)=2(1)

a(1)=2

a(2)=2(2)

a(2)=4

etc.
