What is the sum of the first four terms of sequence S?

(1) After the first two terms of S,the value of each term of S is equal to the average (arithmetic mean) of the last two preceding terms.
(2) The average (arithmetic mean) of the first three terms of S is 10.

a)
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked
b)
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked
c)
BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient
d)
EACH statement ALONE is sufficient to answer the question asked
e)
Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed

Correct answer is option 'E'. Can you explain this answer?

What is the sum of the first four terms of sequence S?(1) After the fi...

Statement (1) states that after the first two terms of S, each term is equal to the average of the last two preceding terms. This information alone is not sufficient to answer the question. We don't have any information about the values of the first two terms or any specific pattern that allows us to determine the sum of the first four terms.

Statement (2) says that the average of the first three terms of S is 10. This information alone is not sufficient to answer the question. Knowing the average of the first three terms does not provide enough information to determine the sum of the first four terms.

Since neither Statement (1) nor Statement (2) alone is sufficient to answer the question, the answer is E: Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.

Similar GMAT Doubts

An arithmetic sequence is a sequence in which each term after the first is equal to the sum of the preceding term and a constant, which is also known as the common difference of that arithmetic sequence. The sequence S contains all the terms of two different increasing arithmetic sequences P and Q such that the number of terms in sequence S is equal to the sum of the number of terms in sequences P and Q. If each of the arithmetic sequences P and Q consists of 10 positive integral terms, how many distinct terms does sequence S have?(1) The least common multiple of the common differences of the sequences P and Q is 6(2) The third term of the sequence P is equal to the second term of the sequence Q

An arithmetic sequence is a sequence in which each term after the first is equal to the sum of the preceding term and a constant, which is also known as the common difference of that arithmetic sequence. An increasing arithmetic sequence N consists of a set of distinct negative integers and an increasing arithmetic sequence P consists of a set of distinct positive integers. The sequence C contains all the terms of arithmetic sequences N and P such that the number of terms in sequence C is equal to the number of terms in arithmetic sequences N and P. Is sequence C an arithmetic sequence?(1) The sum of the largest term of the sequence N and the smallest term of the sequence P is zero.(2) For every integer in sequence N, there exists an integer in sequence P with the same magnitude.
