Answer:
, where n = 1,2,3,4,.....
Step-by-step explanation:
The given sequence : 1, 8, 27, 64, ….
We observe that the terms are perfect cubes of consecutive integers (starting from 1) .
Terms can be written as:
First term = 
Second term=
Third term = 
Fourth term =
Thus , for any nth term ,the formula for the sequence is :
, where n = 1,2,3,4,.....
We are given
first term is 1
so, 
each succeeding term is found by adding 3 to the one before it
so, common difference is

Since, this is arithematic sequence
so, we can use nth terms formula

now, we can plug values
and we get
