Asequence can be defined by the explicit formula . which recursive formula represents the same sequence of
a.
b.
c.
d.

Option: C is the correct answer.

            C.  

The sequence is given by the explicit formula as:

where is the nth term of the sequence.

Also, the first term of the sequence is:

i.e.

Also,

   Hence, the recursive formula which represents the same sequence is:

                          Option: C

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

care to share were the trapezoid shown is ?
