Answer:
x>3, the last option with the open circle
Step-by-step explanation:
Answer:
Coldest has - 2° C while warmest had 2 °C
Option c (9,2)
option c (9,2)
Rule: second differences are 2.
Selection C is appropriate.
_____
First differences are the sequence of differences of the given numbers:
.. 3 -8 = -5
.. 0 -3 = -3
.. -1 -0 = -1
.. 0 -(-1) = 1
Second differences are the sequence of differences of these:
.. -3 -(-5) = 2
.. -1 -(-3) = 2
.. 1 -(-1) = 2
All of these are 2, so the sequence can be described by a *second* order polynomial (because *second* differences are a non-zero constant).
1st option
-2 is -1 + -1
3= +1+1+1
