The general term for the sequence is n+2.
Answer:
it's length is 15cm
Step-by-step explanation:
let a represent the length
a × 10 ×12 = 1800
a×120= 1800
a = 1800÷12
a=15cm

Let
be the line given by the vector equation
.
First, we use the director vectors of the lines L1 and L2 to get the
vector equation of the plane containing them, which we denote by
. This is,

We observe that
. Therefore, the vector equation of
defines a plane and
is a normal vector to 
Finally, the vector equation for the wanted plane, which we denote by
, is
Thus, if
, then
and since
is parallel to
, then it is perpendicular to
.
