Best ResponseYou've already chosen the best response.1Just pattern recognition... The mean of the 1st line is \(2\). The mean of the 2nd line is \(5\). The mean of the 3rd line is \(10\). The mean of the 4th line is \(17\). You're just adding 3, then adding 5, then adding 7, then adding 9... and so on
