Question

Find the sum of the next two numbers in the series below

Answer 1

Answer:

74 and 110

Step-by-step explanation:

lay out the numbers and the difference between the numbers:

20,24,33,49

  +4 +9 +16

and notice the different between the amount added between the numbers

4,9,16

+5 +7

It seems the amount added to the amount added increases by 2 each time

the next two numbers in the sequence above is 9 and 11.

From that we can try to figure out what will be added to the original number by adding 9 and 11 to the difference list.

4, 9, 16, 25(added 9), 36(added 11)

and we can test those values

20,24,33,49,74(added 25),110(added 36)
