Hello,

$u_{1}=7\\
 u_{2}=2*7\\
 u_{3}=2^{2}*7\\
 u_{4}=2^{3}*7\\\\

 u_{n}=2^{n-1}*7\\\\

 u_{10}=2^{9}*7=3584\\

Let's find the inverse of given function ~

$\qquad \sf \dashrightarrow \: f(x) = 2x - 1$

$\qquad \sf \dashrightarrow \: 2x = f(x) + 1$

$\qquad \sf \dashrightarrow \: x = \cfrac{f(x) + 1}{2}$

[ now, replace f(x) and x with $\sf{ {f}^{-1}(x)}$ ]

$\qquad \sf \dashrightarrow \: f {}^{ - 1} (x) = \cfrac{x + 1}{2}$

That's the required inverse function ~

The 3 angles when added together make a straight line which is 180 degrees. To find x subtract the 2 known angles from 180.

The answer would be x = 180 - (67 + 52)

Answer:

0 is neutral when used in integers. When two integers are the same distance away from 0, on opposite sides of the number line, they are opposites.
