A linear pattern.
They are 7, 10, 13, 16 and 19.
There is an interval of 3 between the numbers 1+3=4 4+3=7 7+3=10 10+3=13 13+3=16 16+3=19 19+3=22 22+3=25
8/19 + 7/13 = 237/247
2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13
A linear pattern.
13(13) into 0(7) dump 7 6(13) into 0(7) fill 13 13(13) into 6(7) dump 7 12(13) into 0(7) dump 7 5(13) into 7 fill 13 13(13) into 5(7) dump 7 11(13) into 0(7) dump 7 4(13) into 0(7) fill 13 13(13) into 4(7) left with 10/13 7(7) into 0(19) fill 7 7(7) into 7(19) fill 7 7(7) into 14(19) 19(19) into 5(7) dump 7 17(19) into 0(7) left with 10(19)
They are 7, 10, 13, 16 and 19.
1, 7, 13, 19, 91, 133, 247, 1729 The prime factors are 7, 13, 19
21 and 13. The pattern is t(n) = (-n4 + 10n3 - 23n2 + 38n - 12)/12
To find the pattern, simply look for the difference in the first two numbers, then the following pair of numbers, etc. 2 9 5 13 10 19 17 2 + 7 = 9 9 - 4 = 5 5 + 8 = 13 13 - 3 = 10 10 + 9 = 19 19 - 2 = 17 The pattern is +7, -4, +8, -3, +9, -2...
7 x 13 x 19 = 1729
