When n = 2
First,
m = 6n² + 1
m = 6(2)² + 1
m = 25
Then,
l = [tex]\sqrt{m - 7}[/tex]
l = [tex]\sqrt{25 - 7}[/tex]
l = [tex]\sqrt{18}[/tex]
So when n = 2 l = [tex]3\sqrt{2}[/tex]
When n = 6, we do the same thing but with 6,
First,
m = 6n² + 1
m = 6(6)² + 1
m = 217
Then,
l = [tex]\sqrt{m - 7}[/tex]
l = [tex]\sqrt{217 - 7}[/tex]
l = [tex]\sqrt{210}[/tex]
So when n = 6, l = [tex]\sqrt{210}[/tex]
Hope this helps, good luck! :))
(also the l looks like an uppercase i, sorry about that )
