If you would like a list of the steps/formula, message me and I'll send it to you as it's too long to post here. The answer to your question would be <span>a21 = 162.

Hope this helped, and if it did I'd appreciate if you marked me as brainliest as I need it to get to a higher rank. If you need any more help, feel free to add me and/or message me :)
