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
The spacing is 6 1+6=7 7+6=13 13+6=19 19+6=25 so the missing number in the sequence is 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.
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...
21 and 13. The pattern is t(n) = (-n4 + 10n3 - 23n2 + 38n - 12)/12
1, 7, 13, 19, 91, 133, 247, 1729 The prime factors are 7, 13, 19
They are 7, 10, 13, 16 and 19.
7 x 13 x 19 = 1729
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
7
its 13 14 14 3 5 5 6 7 7 19 20 20 its simple math haha pwned
