205. it is not that hard to figure out. :P
Factor out each term by term to get: 5 x 7007 = 5 x 7 x 1001 = 5 x 7 x 13 x 77 = 5 x 7² x 11 x 13
7 x 11 x 13 = 1001
Can not be determined without the starting number in the series or n sub1
x - 7 - 4 = 13 (-7 - 4 = -13) x - 11 = 13 add 11 to both sides x = 24
7.07
n = 100 + 7 = 107
The nth term is: 2n+7 and so the next number will be 19
2n + 1
It is 4n-13 and so the next number will be 11
7, 11, 13
It is because 7*11*13 = 1001. so abcabc = abc*1001 = abc*(7*11*13)
5 * 7 * 11 * 13 * 13
Factor out each term by term to get: 5 x 7007 = 5 x 7 x 1001 = 5 x 7 x 13 x 77 = 5 x 7² x 11 x 13
7 x 11 x 13 = 1001
Least Common Multiple (LCM) for 7 11 13 is 1,001.
7 * 11 * 13 * 6 = 6,006
It is: 3*7*11*13 = 3003
