Consider this infinite sequence:

          a, b, c, (a+b+c)/3, (a+4b+4c)/9, (4a+7b+16c)/27 .....

where, each of a, b and c is a real number and, each term after the third is the arithmetic mean of the three previous terms.

Determine the limit of the sequence in terms a, b and c.

Just use data sets
