Ah hah! You didn't say so, but you must be talking about 2 and 3 ... the only two

consecutive numbers that are both prime numbers. There can't be any others.

Because if you have any other two consecutive numbers, one of them has to be an even

number ... divisible by 2. Since that number is divisible by 2, it's not a Prime number.

Find all pairs of consecutive prime numbers?

The only two consecutive numbers that are both prime are 2 and 3. Since there are no other even prime numbers (other than 2), there are no more pairs of consecutive prime numbers. Therefore, the term "twin primes" usually refers to pairs of prime numbers that are 2 numbers apart. Examples are (3, 5), (5, 7), (11, 13), (101, 103), and many others more. It is not currently know whether there are infinitely many twin primes.

What are two pairs of consecutive numbers that add up to 5280?

Although not specified as such, "consecutive" requires the numbers to be integers. Two pairs literally means four numbers but there are not four consecutive integers that add up to to 5280. 1318 + 1319 + 1320 + 1321 = 5278 and 1319 + 1320 + 1321 + 1322 = 5282. Four consecutive numbers must add up to an even number that is not a multiple of 4. If by two pairs, the question meant ONE pair (!!), again there is no answer since the sum of any pair of consecutive numbers must be an odd number.

What are the whole consecutive numbers 110 lie between?

The whole consecutive numbers that 110 lies between are 109 and 111. In mathematics, when we say a number lies between two other numbers, we mean that it is greater than the lower number and less than the higher number. In this case, 110 is greater than 109 and less than 111, making it lie between these two consecutive numbers.
