Question 1: The distance between the first two numbers is 3, then between the next two is 4, then between the next two is 5 and so on and so forth. The distance between the last two numbers is 7, so the distance between the last number and the next will be 8. This means the last number is 27 + 8 = 35.
Question 2: The distance between the first two numbers is 3, then 5 for the next two, then 7 for the next two. Therefore, the distance between them increases by 2 each time. The distance between the last two is 11. This means the distance between the last one and the next will be 11 + 2 = 13 and so the last number is 37 + 13 = 50
Question 3: We are dividing the previous number by -5 to get the next number in this sequence. Therefore the last number is -1 / -5 = 1/5 or 0.2.
