Question

The nth term of a sequence is n(n - 1).

What are the first four terms?

What is the 50th term?

Is 59 a term in the sequence?

Which term is 182?
The ______ th term ​

Answer 1

T1=0

T2=2

T3=6

T4=12

T50=2450

59 is not a term in the sequence

Explanation:

Tn=n(n-1)

182=n2 - n

0=n2 - n - 182

0=n2-14n+13n-182

0=n(n-14)+13(n-14)

0=(n-14) (n+13)

Since n cannot be negative n is not equal to -13

Therefore,

n=14
