Write the 7^th term of the sequences whose n^th term is a₇ = n²/2ⁿ

Solution:

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

Here nth term is given as aⁿ = n²/2ⁿ

To find a₇

We need to replace n with 7.

Substituting n = 7

a₇ = 7²/2⁷

= 49/128

Write the 7^th term of the sequences whose n^th term is a_n = n²/2ⁿ

Summary:

We know that the n^th term is a_n = n²/2ⁿ. So, the 7th term of the sequence is 49/128
