S is a set of 85 consecutive multiples of 5. If the smallest number in S is 90, then the greatest number in S is
Pick one: A) 158 B) 597 C) 599 D) 402 E) 510

Rationale: "last term = first term + ( total no . of terms - 1 ) consecutive difference s is a set of 85 consecutive multiples of 5 . if the smallest number in s is 90 , then the greatest number in s is first term = 90 ; total terms = 85 ; difference = 5 90 + ( 84 ) 5 = 510 ans e"
Answer: E
