Question 626916
<font face="Times New Roman" size="+2">


Calculate *[tex \LARGE 3\,\cdot\,2^{i\,+\,1}\ -\ 1] when *[tex \LARGE i\ =\ 0]


Remember, *[tex \LARGE a^1\ =\ a\ \forall\ a\ \in\ \mathbb{R}]


Repeat the above calculation for *[tex \LARGE i\ =\ 1], *[tex \LARGE i\ =\ 2], *[tex \LARGE i\ =\ 3], and *[tex \LARGE i\ =\ 4]


Then add up the results of your 5 calculations.


Sorry, I don't do arithmetic for people.
