determine whether 447 is a term of each sequence(s) If so, whitch term is it ?

Question

A.t(n)=5n-3

B.t(n)=24-5

C.t(n)=-6+3(n-1)

D.t(n)=14-3n

E.t(n)= -8-7(n-1)

Answer 1

for the first one,
5n - 3 = 447
5n = 450
n = 90
Yes, 447 is in the sequence and it is term(90)

D)
14-3n = 447
-3n = 433
n = -433/3 , makes no sense, since n must be a natural number
So, 447 cannot be a term in this sequence

Do the others the same way

Answer 2

t(n)=-6+3(n-1)

Answer 3

Thank you guys so much
