What is the nth term of the sequence -4 -9 -14 -19

-44

Step-by-step explanation:

first term is -4, second -9, third -14, fourth -19, etc.

there is constant difference (-5) between each two neighbor terms

you can use calculator by pushing the following buttons: -4-5

the method is:

1) insert first term (-4)

2) insert a difference (-5)

3) push the "=" button 1 time less than the desired term number

So, if you must find 9th term, you push "=" button 8 times

after pushing buttons -4-5 you get a result -44 on a calc
