That would be

@weights[3..-1].each_index{|i|
}

(OP said "greater than 2".)

But it does not work because each_index will start at 0.  Rather you
probably meant

@weights[3..-1].each {|elem|
}


For the indexes only one can do

(3...@weights.size).each {|i|
}

or

for i in 3...@weights.size
end

Kind regards

robert
