What is sequence?

Find the next three terms of the sequence below:

-6, -10, -14,...

• -17, -21, -25

• 17, 21, 25

• 18, 22, 26

• -18, -22, -26

Select the explicit rule that represents the sequence.

• 
  

  $a_n=14\left(-3\right)\left(n-1\right)$

• $a_n=3+14\left(n-1\right)_{ }$

• $a_n=14+3\left(n-1\right)$

• $a_n=-3+14\left(n-1\right)$
