Mohamed and Li Jing were asked to find an explicit formula for the sequence -5\,,-25\,,-125\,,-625,...−5,−25,−125,−625,...Minus,
ANTONII [103]
Answer:
the equation is given as 
Explanation:
As the sequence is given as −5,−25,−125,−625,...
From this the first term is given as
a1=-5
Now the relation between this term and the next term is to be observed.
d=a2-a1=-25-(-5)=-25+5=-20
d=a3-a2=-125-(-25)=-125+25=-100
Now it is observed that the difference is not same this indicates that the relation is not arithmetic.
next up is the geometric sequence so the value of ratio is given as
r=a2/a1=-25/-5=5
r=a3/a2=-125/-25=5
As the ratio is same this indicates, this is a geometric sequence.
Now for the geometric sequence, the value of the general term is given as
Here a1=-5 and r=5 so the equation is given as
The external crust of the Earth consists of a series of tectonic plates moving on the planet's surface. Often volcanoes are created in regions where the plates come together. Volcanoes also can grow in the middle of a rock, which is named "Hot Spot," where the magma rises up until it bursts on the sea floor. A hot spot in the center of the Pacifical Rock is created on the Hawaiians Islands. The plate shifts, while the hot spot remains set. So the chain of the islands that comprise the Hawaiian Island chain was formed when this plate moved over the hot spot.

I believe C is the correct answer; parent material is rich in nutrients for plants, and decomposed plant litter is also known as decaying organic material. Hope this helps! :)
a. Sea-to-land breezes blow in an (On shore) direction.
b. (Convectional) currents are circular movements of rising and descending air.
c. Land-to-sea breezes (local winds) occur during (daytime).
d. During the day, air above the sea is (Cooler) than the above land.
