WebOct 30, 2015 · 1 For n = 2 we have ∑ i = 1 n ( 2 i − 1) = ( 2 − 1) + ( 4 − 1) = 1 + 3 = 4 = n 2. :) Oct 30, 2015 at 10:53 Right, we have to consider both. not only the the last one. thanks a lot. Now it is all clear. – Oct 30, 2015 at 10:57 Add a comment 1 First, show that this is true for n = 1: ∑ i = 1 1 2 i − 1 = 1 2 Second, assume that this is true for n: WebAnd now we can do the same thing with this. 3 times n-- we're taking from n equals 1 to 7 of 3 n squared. Doing the same exact thing as we just did in magenta, this is going to be equal to 3 times the sum from n equals 1 to 7 of n squared. We're essentially factoring out the 3. We're factoring out the 2. n squared.
