Question

105 91 203 49 (70) 299 143 221 65 (?) A)130 B) 26 C) 182 D) 104

Answer 1

Ответ:

а) 130

Пошаговое объяснение:

Тут у всех чисел нужно найти общий делитель, и умножить на 10.

Например у первого ряда общий делитель 7, умножаем на 10 получается 70

На втором же общий делитель 13. Умножаем на 10 и получится 130

Answer 2

To find the missing number in the sequence 105, 91, 203, 49, 70, 299, 143, 221, 65, (?), you need to look for a pattern or rule that governs the sequence. Let's analyze the given numbers to see if we can identify any patterns.

Looking at the sequence, we can observe the following pattern:

105 - 14 = 91 91 + 112 = 203 203 - 154 = 49 49 + 21 = 70 70 + 229 = 299 299 - 156 = 143 143 + 78 = 221 221 - 156 = 65

Based on this pattern, it seems that the sequence is alternating between subtracting and adding a specific number. Let's continue this pattern to find the missing number:

65 + 78 = 143 143 - 156 = -13

Therefore, the missing number in the sequence is -13.

Now let's check the options given:

A) 130 B) 26 C) 182 D) 104

None of the given options (-13) match the missing number in the sequence. It's possible that there might be an error in the given options or the pattern we identified is not correct. Please double-check the options or provide more information if available.
