Use delete_at - and read the documentation.

array.delete_at(index). use this to delete particular indexes in an
array.

Hi Vamsi and Robert,

delete_at(index) is useful when need to delete one data. But i want to
delete series like 1,3,5,7. Currently i am using loop for it. Any other
good code for it.

I tried Array.delete_at(1,3,7,9) --> Like this

If there is no duplicate data, you can use values_at like this

a = a - a.values_at(1,3,5,7)

If there is no duplicate data, you can use values_at like this
(...)

Or apply Array#- to the indexes. This works with duplicate data, too:

a.values_at(*((0...a.size).to_a - [1, 3, 5, 7]))
