# Write the 7^{th} term of the sequences whose n^{th} term is a_{7} = n^{2}/2^{n}

**Solution:**

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

Here nth term is given as a^{n} = n^{2}/2^{n}

To find a_{7}

We need to replace n with 7.

Substituting n = 7

a_{7} = 7^{2}/2^{7}

= 49/128
