Title: Question for mathematic brainiacs
Post by: spirithorse on June 14, 2014, 10:50:03 pm

In this sequence of numbers

1  -  8  -  27  - ? -  125  -  216

What is the missing number to complete the sequence? (What number should be in the question marks' place?)
Would anyone that is positive of the answer please explain to me how they derived at that number?
Thanks and God Bless! Spirithorse

The missing number is 64.  The numbers you wrote are cubes of whole numbers.
1 cubed = 1
2 cubed = 8   ( 2 x 2 x 2 = 8 )
3 cubed = 27
4 cubed = 64
5 cubed = 125
6 cubed = 216
