A cricket player played n (n>1) matches during his career and made a total of (n^2-12n+39)(4.6^n-5.3^n+1)/5 runs. If Tr represents the runs made by the player in r^th match such that T1 =6 and Tr = 3Tr-1 +6^r, r E [2,n] then find n?

Hi,

There is some information missing in the question.
By T1 and TN we can find the sum of series in N but again the given expression is also in N so we can verify it but we dont have any other info to find N. So please check the question and post again.
