Use Raptor programming tool to design algorithms:

$1.$ Calculate the sum of odd numbers from $1$ to n$.$ Find the output when n is $13.$

$2.$ Find out how many numbers between n$1$ and n$2$ are multiples of $3$ but are not multiples of $2.$ Find the output when n$1$ is $13$ and n$2$ is $27.$

$3.$ Calculate the average of numbers between n$1$ and n$2$ that are multiples of $3$ but are not multiples of $2.$ find the output when n$1$ is $13$ and n$2$ is $27.$
