The infinite sequence of geometric terms is divergent if you try to add up all the terms. Sure the first 20 terms will add up to a fixed number but this isn't true for an infinite number of terms. The reason why the infinite series diverges is because r = 1.1 is larger than 1. If r > 1 then the infinite series diverges. It only converges if -1 < r < 1.
To write this in sigma notation, you would write

which is the result of adding the terms of 100(1.1)^(n-1) for n = 1 all the way up to n = 20. You can compute this by hand or preferably with a calculator or spreadsheet program
Answer:
8600 litre×235 will be there in the tanks
It's the last one
these are 2 ways of writing the function 'f of g(x)'.
125m-75m+43,875=45,450-175m
We simplify the equation to the form, which is simple to understand
125m-75m+43,875=45,450-175m
We move all terms containing m to the left and all other terms to the right.
+125m-75m+175m=+45.45-43.875
We simplify left and right side of the equation.
+225m=+1.575
We divide both sides of the equation by 225 to get m.
m=0.007
(I’m sorry if I’m wrong I tried)
