.
The fifth term in the sequence would be 161.
Step-by-step explanation:
We have to find the fifth term in the sequence
Given that
a1 = 1 (that is the first term)
If we follow the formula, the value of every term depends on the value of immediate lower term. Therefore, the a2 can be calculated by putting 2 in place of n in above equation
as a1 = 1
Similarly,
as a2 = 5
and
as a3= 17
and
as a4 = 53
Therefore, the fifth term in the sequence would be 161.

Step-by-step explanation:
5x2=10 3x4=12 2x2=4 6x1=6
The two trapezoidal faces together have an area of
.. (5 in)*(5 in +9 in) = 70 in^2
The remaining surface can be unfolded to an area that is
.. (5 in)*(5 in +9 in +6.4 in +5 in) = 127 in^2
Together, these add to
.. 70 in^2 +127 in^2 = 197 in^2 . . . . . . . the 4th selection
