The next three terms are: -3, 6, and 15

To get each new term, we simply add 9 to the last term. So we add 9 to -12 to get -3. Then we add 9 to -3 to get 6. Finally we add 9 to 6 to get 15

In other words,
first term = -12
second term = first term+9 = -12+9 = -3
third term = second term + 9 = -3+9 = 6
fourth term = third term + 9 = 6+9 = 15

This process repeats forever though we only need three terms in this case.

So that's why the answer is the three values -3, 6 and 15

Jane can type 150 words in 2 minutes. How many<br> words can she type in 5 minutes?
Masteriza [31]
I believe about 750 this is because of you multiply 150 and 5 you get your answer 750 because each 2 minutes she types is 150 and although you can find your average I just add the average 5 times this would be an easier way!!!
