I know how to write a simple rule for a sequence like:
{2, 4, 6, 8, 10, 12, 14, 16, 18, 20, ...} A(n)=2n
but how can I write a rule for sequences like this ?
{2, 4, 6, 12, 14, 16, 22, 24, 26, ...}
or
{2, 4, 10, 12, 14, 20, 22, 28, 30, 32, ...}
and how do I write the rule to start at number 4 and end at 22 ?
Thanks in advance.
