Answer:
Question 1: 20
Question 2: 27
Step-by-step explanation:
Question 1:
Given a sequence is defined by the explicit definition [tex]t_{n} = n^{2} + n[/tex]
Therefore, the 4th term i.e. [tex]t_{4} = 4^{2} + 4 = 20[/tex] (Answer)
So, the third option is correct.
Question 2:
Given a sequence is defined by the explicit definition [tex]t_{n} = 2^{n} - n[/tex]
Therefore, the 5th term i.e. [tex]t_{5} = 2^{5} - 5 = 27[/tex] (Answer)
So, the third option is correct.
