What is the next number

1,5,9,15,?:confused:

I have given four number... Find out the fifth number

Give another two three terms...

Because if you give like this then lots of different logical answers you got..

Here is my first logic answer..

1,5,9,15,21,29,37,....(Logic: diff between two numbers going like 4,4,6,6,8,8..)
