rule describes this sequence is
an = 2 ( n^2 + n )
n = 1
an = 2 ( 1^2 + 1 )
an = 2 ( 1 + 1 )
an = 2 ( 2 )
an = 4
n = 2
an = 2 ( 2^2 + 2 )
an = 2 ( 4 + 2 )
an = 2 ( 6 )
an = 12
n = 3
an = 2 ( 3^2 + 3 )
an = 2 ( 9 + 3 )
an = 2 ( 12 )
an = 24
n = 4
an = 2 ( 4^2 + 4 )
an = 2 ( 16 + 4 )
an = 2 ( 20 )
an = 40
