As the numbers 1 to 99 are multiplied together, one factor of the product will be 10 which means the last digit must be 0 (a zero).

Without working out the product, it can be seen that every multiple of 5 in the original numbers can be paired up with an even number (that is not a multiple of five) and multiplied together (which produces a multiple of 10) which are all factors of the product together; thus the product will ends with that number of zeros: there are 19 multiples of 5 in the numbers 1-99, so the last 19 digits of the product are all 0 (zero).

What expression can be used to find the next term in this pattern 0 4 12 24 40?

There is no possible way to determine this. To get from 0 to 4 is +4. Multiplied by 3 to get 12. Multiplied by 2 to get 24. From 24 to 40 is 1.66666666667. Which is a repeating number, no pattern is followed, therefore making it illogical

What can you multiply to get to 110?

For any number x, you can multiply any of it's factors by x/factor to get x. For 110, 11 is a factor, and 110/11 is 10. So 10 * 11 = 110. In the case of 110, all of the factors are as follows: 1, 2, 5, 22, 55, 110 There is a pattern here; the first and last numbers multiplied together will give you the value 110, and then the 2nd numbers from the front and back will multiply to get 110, and so on. This is true for all integers. If you find the prime factorization of the number, you can determine all the possible combinations of multiplying numbers to get the original number, that is to say, where you can multiply 3, 4 or more numbers together to get the original number. For example, the prime factorization of 110 is as follows: 2, 5, 11. So you can see that 2*5*11=110 as well.
