1, 2, 5, 10, 25, 50, 125, 250, 625, 1250, 3125, 6250, 15625, 31250.
2 | 2505 | 1255 | 255 | 51 | 1250 = 2 × 5 × 5 × 5
5 to the power of 2 plus 15 to the power of 2 = 250
Here's how to do this in your head: 55 X 25 = (10 + 10 + 10 + 10 + 10 + 10/2) X 25 = (10 X 25) + (10 X 25) + (10 X 25) + (10 X 25) + (10 X 25) + (10/2 X 25) = 250 + 250 + 250 + 250 + 250 + 250/2 = 500 + 500 + 250 + 125 = 1250 + 125 = 1375 You can expand this method out to three, four, even five digit numbers, and if you practice enough, you'll soon be impressing all of your friends around the D & D table with your calculator-like brain! If you know the FOIL method (First, Outer, Inner, Last) you can make this even easier. Pay attention because we're getting pretty advanced now: 55 X 25 = (50 + 5) X (20 + 5) = 50 X 20 (the first terms) + 50 X 5 (the outer terms) + 5 X 20 (the inner terms) + 5 X 5 (the last terms) = (50 X 10 X 2) + (50 X 10 / 2) + (5 X 10 X 2) + (5 X 5) = (500 X 2) + (500/2) + (50 X 2) + 25 = 1000 + 250 + 100 + 25 = 1375. If you're comfortable with multiplying and dividing by 2, which you should be, what's written above takes approximately 5 seconds to do in your head.

Without knowing what object the number sequence is attached to there can be no easy answer
2500 - 1, 2, 4, 5, 10, 20, 50, 125, 250, 500, 625, 1250, 2500 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500, 625, 1250, 2500
50 Each term in the sequence is 5 times the previous term.
The factors of 1250 are 1, 2, 5, 10, 25, 50, 125, 250, 625, and 1250.The factor pairs of 1250 are 1 x 1250, 2 x 625, 5 x 250, 10 x 125, and 25 x 50.The proper factors of 1250 are 1, 2, 5, 10, 25, 50, 125, 250, and 625 or,if the definition you are using excludes 1, they are 2, 5, 10, 25, 50, 125, 250, and 625.The prime factors of 1250 are 2, 5, 5, 5, and 5. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The distinct prime factors of 1250 are 2 and 5.The prime factorization of 1250 is 2 x 5 x 5 x 5 x 5 or, in exponential form, 2 x 5^4.1250 = 2 * 5 * 5 * 5 * 5Asking for prime factor and prime factors is the same thing, so:1250: 2 * 5 * 5 * 5 * 5or 2 * 5^4
It is: 2*5*5*5*5 = 1250 or as 2*5^4 = 1250
The factors of 250 are 1, 2, 5, 10, 25, 50, 125, and 250. The multiples of 250 are 250, 500, 750, 1000, 1250, 1500, 1750, 2000, 2250, 2500, and so on.
