The answer is 608.

The sum of -5 plus 11 is 6. When a negative is added to the positive you subtract instead of add to get your answer.
-6
The sequence alternates between multiplying by 2 and then subtracting 3. Starting with 5, you multiply by 2 to get 10, then subtract 3 to get 7, multiply by 2 to get 14, subtract 3 to get 11, multiply by 2 to get 22, and subtract 3 to get 19. Following this pattern, the next operation is to multiply 19 by 2, resulting in 38. Therefore, the next number in the series is 38.
11 and 7 Add them and you get 18, subtract them and you get 4.
11
28 ÷ 4 x 3 - 10 = 11
The numbers that multiply to 30 and add up to 11 are 5 and 6. Specifically, 5 × 6 = 30 and 5 + 6 = 11.

Yes, there is a method for determining divisibility by 11, which involves checking the alternating sum of the digits in a number. To do this, subtract the sum of the digits in the odd positions from the sum of the digits in the even positions. If the result is either 0 or divisible by 11, then the original number is also divisible by 11. This method can also be used to directly divide a number by 11, but it may require further calculations to find the quotient and remainder.
Product means to multiply the operands. The product of 5 and 6 is 30. Sum means to add the operands. The sum of 5 and 6 is 11.
Yes. Choose any three consecutive counting numbers. The first number is the second number subtract 1 The third number is the second number add 1 Adding the three numbers together is the same as adding: (the second number subtract one) plus the second number plus (the second number add one). The "subtract one" and "add one" cancel each other out to leave the sum as: the second number plus the second number plus the second number Which is the same as 3 times the second number, ie the sum is a multiple of 3 and so is divisible by 3. For example: 10 + 11 + 12 = (11 - 1) + 11 + (11 + 1) = 11 - 1 + 11 + 11 + 1 = 11 + 11 + 11 + (1 - 1) = 11 + 11 + 11 + 0 = 11 + 11 + 11 = 3 x 11
