Find three numbers in an arithmetic sequence, where the sum of the second and third is 12, and the product of the first and second is 5.
First term== sqrt(51) - 6
2nd term == 1/3 (6 + sqrt(51))
3rd term == 1/3 (30 - sqrt(51))
[sqrt(51) - 6] * [1/3 (6 + sqrt(51))==5, and:
[1/3 (6 + sqrt(51))] + [ 1/3 (30 - sqrt(51))]==12
