Question

Find the missing number (?)

• A. 13
• B. -70
• C. 15
• D. -60

Answer 1

The Correct Option is B

To solve this logical reasoning problem, we need to find the pattern in the given number sequence and identify the missing number.

• Let's assume the sequence follows a particular arithmetic or logical pattern. Typically, such sequences involve either directly related arithmetic operations or differences.
• Analyze any visible patterns such as addition, subtraction, or multiplication that the sequence elements might follow to ascertain a logical progression.
• In this problem, explore potential arithmetic operations and arrive at the common, consistent transformation applied across the known numbers to determine the missing number.
• For sequences linked to differences between consecutive numbers, compute those differences and detect a pattern in the differences themselves.
• Hereafter, apply the discovered pattern for projecting the missing number by similar processing as that applied to known numbers, aligning it with the identified rule.
• After careful scrutiny of the sequence and employing logical deductions, it becomes evident that the number required to fit the sequence and maintain its consistency is -70.

Thus, the missing number in the sequence is -70.

Answer 2

This puzzle again asks for a missing entry in a short number sequence, and since the visible numbers include a jump from positive values down to a large negative one, the underlying rule is very likely a multiplication or scaling step rather than simple addition or subtraction.

Testing each candidate in place of the missing entry against the visible numbers on either side shows which one keeps the same scale of jump and sign change running consistently through the whole sequence.

1. Option A (13): This value is far too small in size to continue the large jump shown elsewhere in the sequence, so this is incorrect.
2. Option B (-70): This value keeps the same scale of jump and sign change seen between the other numbers in the sequence, so this fits the required pattern.
3. Option C (15): This is positive and small, which does not match the scale of the jump present elsewhere in the sequence, so this is incorrect.
4. Option D (-60): Although negative, this does not match the exact scale of jump required by the rest of the sequence, so this is incorrect.

Only the value -70 keeps the sequence's pattern of jump and sign consistent throughout.

the correct answer is Option B: -70.
