Explanation:
It appears that the rate of change for this sequence is +3 because since t(1) = 11 and t(3) = 17, it would make sense that t(2) = 14.
From there you can use a calculator and start from 17 and keep adding 3 until you notice a number that doesn't belong in the sequence.
Hope this helps! I apologize if I'm incorrect
