In terms of Sequence are t1, t2, t3, ....tn, what is value of n?
1) Sum of n terms is 3124
2) Average of n terms is 4
Given : The terms t1,t2,t3,t4...., tn are in sequence. But we don't know which sequence this is
DS : value of n
Statement 1: t1 + t2 + t3 +t4 +.... + tn = 3124
NOT SUFFICIENT
Statement 2: (t1 + t2 +t3 + t4 +... + tn )/n = 4
-> (t1 + t2 +t3 + t4 +... + tn ) = 4n
NOT SUFFICIENT
Combined : 4n = 3124
SUFFICIENT
Answer C
