S is a set of 64 consecutive multiples of 4. If the smallest number in S is 68, then the greatest number in S is  Pick
A) 198
B) 297
C) 320
D) 402
E) 405

Rationale: last term = first term + ( total no . of terms - 1 ) consecutive difference s is a set of 64 consecutive multiples of 4 . if the smallest number in s is 68 , then the greatest number in s is first term = 68 ; total terms = 64 ; difference = 4 68 + ( 63 ) 4 = 320 ans c
Answer: C
