Question

Given the sequence is defined by the explicit definition t_n=2^n-nt n = 2 n − n, find the 5th term of the sequence. (ie: t_5t 5)

Answer 1

Answer:

If the n-th term of a sequence  be , t(n) equal to  $2^{n} - n$  then the 5-th term is 27 but if the n-th term is (2n -n) then the 5-th term is 5.

Step-by-step explanation:  

If the n-th term of a sequence  be , t(n) = $2^{n} - n$

then, the 5-th term is given by,  t(5) = $2^{5}- 5$

                                                          = 32 - 5

                                                          = 27

If the n-th term of a sequence  be , t(n) = 2n - n = n

then, the 5-th term is given by,  t(5) = 5
