Write the 20th term of the sequences whose n^th term is a_n = n(n - 2)/(n + 3)

Solution:

The sequence is a list of numbers (or items) that exhibits a particular pattern.

nth term is given as:

a_n = n(n - 2)/(n + 3)

Substituting n = 20, we get

a₂₀ = 20(20 - 2)/(20 + 3)

= 360/23

Write the 20th term of the sequences whose n^th term is a_n = n(n - 2)/(n + 3)

Summary:

Given that the nth term of the sequence is a_n = n(n - 2)/(n + 3), we found out that the 20th term of the sequence is 360/23
