Answer 1

Это последовательность номер 4.

Answer 2

1) 540, 440, 340, 240 - The rule states that each subsequent number is 10 less than the previous number. - Starting with 540, we subtract 10 to get the next number: 540 - 10 = 530. - Continuing this pattern, we subtract 10 from each subsequent number to get the next number in the sequence: 530 - 10 = 520, 520 - 10 = 510, and so on. - Therefore, the sequence is 540, 530, 520, 510, 500, ...

2) 99, 89, 79, 78 - Following the given rule, each subsequent number is 10 less than the previous number. - Starting with 99, we subtract 10 to get the next number: 99 - 10 = 89. - Continuing this pattern, we subtract 10 from each subsequent number: 89 - 10 = 79, 79 - 10 = 69. - However, it seems there is a mistake in the sequence you provided because the next number should be 69, not 78. - Therefore, the corrected sequence is 99, 89, 79, 69, ...

3) 100, 110, 120, 130 - Here, the rule states that each subsequent number is 10 more than the previous number. - Starting with 100, we add 10 to get the next number: 100 + 10 = 110. - Continuing this pattern, we add 10 to each subsequent number: 110 + 10 = 120, 120 + 10 = 130. - Therefore, the sequence is 100, 110, 120, 130, ...

4) 110, 100, 90, 80 - In this sequence, each subsequent number is 10 less than the previous number. - Starting with 110, we subtract 10 to get the next number: 110 - 10 = 100. - Continuing this pattern, we subtract 10 from each subsequent number: 100 - 10 = 90, 90 - 10 = 80. - Therefore, the sequence is 110, 100, 90, 80, ...
