From one number to the next you add one to each addition... 1 to 5= +4 5 to 13= +8 (+ 4 from last) 13 to 26= +13 (+ 5 from last) 26 to 45= +19 (+ 6 from last) 45 to 71= +26 (+ 7 from last)

1 x 26, 2 x 13, 13 x 2, 26 x 1.
Some equivalent fractions of 39/45 are: 13/15 = 26/30 = 39/45 = 52/60 = 65/75
With only two numbers it is difficult to find a pattern but I would imagine that this is a simple one since those are the only two numbers provided. If you do 21-13=8 you see that the difference is 8 so therefore, you would add 8 to each continuing number of the sequence. The pattern would be 13, 21, 29, 37, 45, 53, 61, 69
26/45 cannot be simplified.
45
2 times 13 equals 26. 1 times 26 also equals 26.
2 x 13 = 26 3 x 3 x 5 = 45
26
1 x 26, 2 x 13, 13 x 2, 26 x 1.
They are: 13 to 15 and 39 to 45
