Question

List the first 5 terms of the sequence -3n -2.
​

Answer 1

-5,-8,-11,-14,-17

Explanation:

-3n -2

n=1 -3(1) -2 = -3-2 = -5

n=2 -3(2) -2 = -6-2 = -8

n=3 -3(3) -2 = -9-2 = -11

n=4 -3(4) -2 = -12-2 = -14

n=5 -3(5) -2 = -15-2 = -17

Answer 2

We can substitute n with each term in order.

First Term:

-3(1) - 2

-3 - 2

-5

Second Term:

-3(2) - 2

-6 - 2

-8

Third Term:

-3(3) - 2

-9 - 2

-11

Fourth Term:

-3(4) - 2

-12 - 2

-14

Fifth Term:

-3(5) - 2

-15 - 2

-17

Therefore, the sequence is -5, -8, -11, - 14, -17

Best of Luck!
