If you say "The steps are not in the right order" I understand: Everything are not going as it should be. If you say "The steps are not in the right sequence" I understand: the steps should fallow specific order (for example numbered) but it isn't. Take care

Hi Felicity, In these sentences, they have the same meaning,i.e. the steps follow each other, so you can choose either word. The wonderful thing about English is that you can choose from a variety of words which have similar meanings. However, in these sentences the meaning depends on the context. * I organised the cash in ascending order. Following numbers $1, $2 etc * The paragraph should follow a particular sequence. The meaning here is not about a numbered or even an alphabetical order. It's a different kind of order i.e. topic sentence, body, conclusion. It implies an expected pattern or structure but still in that order which means that you can't have the conclusion first. Sometimes the context in which the word is written will help you choose the best word. I hope that helps. :)
