"+-" should always be changed to "-".
You have 3 - 7 - 2. You may evaluate this from left to right, obtaining -4 -2, or -6.
4 - 16 -2(2) involves multiplication, which must be carried out before addition or subtraction. Thus, 4 - 16 - 4. Working from left to right, we get -12 - 4 = -16
Which one do you need an answer to?
Answer:
-3
Step-by-step explanation:
Simplified polynomial: 4x^2 + 2x - 5
Plug in -1: 4(-1)^2 + 2(-1) - 5
= -3
The next number in the series is 30.
<h3>What is series?</h3>
It should be noted that series simply means the operation of adding values together in a data set.
In this case, it can be seen that the numbers are interchangeable between 30 and 31.
In this case, since 31 was the last number, the next number will be 30.
