The nth term of a sequence is 3n+4 explain why 21 is not a term of this sequence

Mathematics
1 answer:
Snowcat [4.5K]3 years ago
6 0

In this sequence, n can only be a natural number. So, if you plug in 5 for n, then you get 19. Also, if you plug in 6 for n, you get 24. Since no natural number can be replaced with n to get 21, it isn’t a term in the sequence

Nat2105 [25]

Answer:

0 or -5/768

Step-by-step explanation:

192x * 4 is 768x

Now you have 768x=-5

If you divide both sides by 768 you get -5/768

In decimal form that is -0.006510416

If you round the decimal to the nearest tenth you get 0

I hope this helps!
