I am having trouble with this pattern.
1-8-27-64-125.
I have tried to find a common multiple, tried add and subtracting. Tried multiple number combinations. What am I missing. Thank you for any help.

Hmmm. I hate to give away the secret! Here' a clue - how about comparing these three sequences:
1, 2, 3, 4, 5, ...
1, 4, 9, 16, 25, ...
1, 8, 27, 64, 125, ...

Another hint:

The second sequence is:

12, 22, 32, 42, 52,.......

the sequence is 13 - 23 - 33 - 43 - 53

No, it's not.

The sequence is \(\displaystyle 1^3, \ 2^3, \ 3^3, \ 4^3, \ 5^3.\)

A sequence has commas between terms.sequence is \(\displaystyle 1^3, \ 2^3, \ 3^3, \ 4^3, \ 5^3.\)

(I am not kidding around.)

Hi,
Thank you for the answer, I would love to know how to find the pattern? Is it simply a question of trying everything until something works or is there a way to calculate the pattern?
Thank you
 
It should be known by inspection that those numbers were all perfect cubes.
 
is there really a minus in between the numbers or did you mean to put commas. It makes a slight difference. You are trying to work out an expression for the nth term. so Un =?
