In this question, it is given that the eighth term is 78 and the explicit formula is

And the recursive formula is

And we have to find the 20th term . And for that, we put 20 for x in the explicit formula. That is

Therefore on using the explicit formula, we will get 198 as the 20th term .
Hello,
N is closed for an opération(µ) means that
a,b ∈ N : a µ b ∈N (i suppose so)
Answer (1) ex 2/3 ∉ N
Answer (4) ex 2-3 ∉ N
∀ a,b ∈ N: a+b ∈N is true ; not a answer.
∀ a,b ∈ N: a*b ∈N is true ; not a answer.
12 chaperones to 210 students....12/210 reduces to 2/35
18/300 reduces to 3/50
20/350 reduces to 2/35
8/160 reduces to 1/20
14/260 reduces to 7/130
so the same ratio would be Jefferson High School
