how many sides does each triangle
and cut them into equal parts
Area=length times width
area=10.5
length=3.5
10.5=3.5 times width
divide both sides by 3.5
3=width
width=3ft

the idea being, you multiply the "x" by some power of 10 that moves the repeating part to the left of the decimal point and the split it like above.
we are given
geometric sequence -36, 6, -1, 1/6, ...
first term is -36

now, we can find common ratio


now, we can find nth term

now, we can plug values
and we get

now, we can find 5th term , 6th term, 7th term
fifth term:


sixth term:


seventh term:


so, next terms are
, 
,
