Step-by-step explanation:
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked
Both statements (1) and (2) TOGETHER are sufficient to answer the question asked; but NEITHER statement ALONE is sufficient
Answer:
Both statements (1) and (2) TOGETHER are sufficient to answer the question asked
Step-by-step explanation:
Given statement 1 :
xy < zy < 0,
The product of two numbers are negative if either of the numbers are negative.
∵ if xy < 0 ⇒ Case 1 : x > 0 and y < 0
Case 2 : x < 0 and y > 0,
Thus, Statement is not sufficient to prove y is positive,
Now, Statement 2 :
x < z, x is negative,
That is, x < 0
Combining statements (1) and (2),
We get,
xy < 0, x < 0,
⇒ y > 0
That is, y is positive.
Hence, Both statements (1) and (2) TOGETHER are sufficient to answer the question asked

Answer:
The nth term of the series is 5-9n.
Step-by-step explanation:
Given : Series 14, 23, 32, 41,..
To find : The nth term of the series ?
Solution :
The given series 14, 23, 32, 41,.. is an arithmetic series as the difference between term is common.
Where, first term is a=14 and common difference d=23-14=9
The nth term of the arithmetic series is
Therefore, The nth term of the series is 5-9n.
