I think the answer is 16.5 sorry if its not right
I would say 20 because if you add the 10 with 10 the other shaded area so that is why i say 20
Given:
The sequence is:
-15,-10,-4, 3, 11, ______
To find:
The next number.
Solution:
We have,
-15,-10,-4, 3, 11, ______
Here, the difference between two consecutive terms are:


Similarly,



It is clear that the difference difference between two consecutive terms is increasing by 1. So, the next difference must be (8+1)=9.
Let the next number be x. Then,



Therefore, the next number of the sequence is 20.
Answer:
3x−4>11
Step 1: Add 4 to both sides.
3x−4+4>11+4
3x>15
Step 2: Divide both sides by 3.
> 
x>5
9514 1404 393
Answer:
C, D
Step-by-step explanation:
The equation factors as ...
(x -3)(x +3) = 0
The value will be zero when a factor is zero. That is, solutions are ...
x = 3 and x = -3 . . . . . matches choices C and D
