Is 9999 in the sequence n²+2n?​

Mathematics
1 answer:
Tamiku [17]2 years ago
8 0

Answer:

No

Step-by-step explanation:

To find out, all we need to do is plug in 9999 into the sequence.

9999 = n^2 + 2n

By completing the square, we get (n+1)^2 = 1001. 1001 is not a perfect square, which means that 9999 is not in the sequence.

hope this helped! :)
