X + 1

Combine like terms, so terms with x go together and terms without an x go together

So 2x - x = x
3 - 2 = 1
That's as simplified as it can be

Answer:

$\frac{45}{4096}$

Step-by-step explanation:

1) q=90/180=45/90=...=1/2;

2) the formula of the n-th term of the given sequence is:

$a_n=a_1*q^{n-1};$

3) according to the formula 15th term is:

$a_{15}=a_1*q^{15-1}=180*\frac{1}{2} ^{14}=\frac{180}{16384} =\frac{45}{4096}$

or ≈0.011.
