When n = 2
First,
m = 6n² + 1
m = 6(2)² + 1
m = 25
Then,
l =

l =

l =

So when n = 2 l =

When n = 6, we do the same thing but with 6,
First,
m = 6n² + 1
m = 6(6)² + 1
m = 217
Then,
l =

l =

l =

So when n = 6, l =

Hope this helps, good luck! :))
(also the l looks like an uppercase i, sorry about that )
