stay safe :)

not sure abt the ans

Answer 2

Answer:

2) n²-1

Step-by-step explanation:

Taking n=1 in n²+1, we get

a1= 2

Taking n=2 in n²+1, we get

a2= 4-1= 3

Taking n=3 in n²+1, we get

a3= 9-1= 8

Here, we can observe that the sequence is not an AP as the common difference is not same.

So, nth term of AP cannot be n²+1.
