Step-by-step explanation:

Find the rule:

2, -6, 18, ...

To get to -6, multiply by -3.

To get to 18, multiply by -3.

The rule is to multiply by -3.

Find the 7th term:

Multiply 18 by -3.

[tex]-18 \times 3 = -54[/tex]

-54 is the 4th term.

Multiply -54 by-3.

[tex]-54 \times -3 = 162[/tex]

162 is the 5th term.

Multiply 162 by -3.

[tex]162 \times -3 =-486[/tex]

-486 is the 6th term.

Multiply -486 by -3.

[tex]-486 \times -3 = 1458[/tex]

1458 is the 7th term.
