Fill in the gaps in this sequence: -8, -19, -30, _ , _.
(Geometric and arithmetic sequences)

-8, -19, -30, -49 , -60

Step-by-step explanation:

Here we have the following sequence :

-8, -19, -30, _ , _

Following sequence was an AP( Arithmetic Progression ) with first term as -8 i.e. and common difference having general equation as : .

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

i'm pretty sure the answer is a. decreases with increase in
