Answer:

(45,9), (50, 5)

Step-by-step explanation:

(14, 5) , (21, 3) , (26, 8) , (33, 6) , (38, 11) , ( _____ , _____ ) , ( _____ , _____ ) , (57, 12) , (62, 8) , (69, 15) , (74, 11

Starting with the first pair in the bracket: 14, 21, 26, 33, 38

It can be seen that 7 is added to 14 to give 21

Then 5 is added to 21 to give 26

This sequence continues that way, add 7 to a number, then add 5 to the next number

38 + 7 = 45

45 + 5 = 50

50 + 7 = 57

57 + 5 = 62

62 + 7 = 69

69 + 5 = 74

This gives 14, 21, 26, 33, 38, 45, 50, 57, 62, 69, 74

Then moving to the next pair, it is the addition of the two digit number of the first pair of the sequence

14

1 + 4 = 5

21

2 + 1 = 3

26

2 + 6 = 8

45

4 + 5 = 9

50

5 + 0 = 5

Therefore, the missing two pairs are

(45,9), (50, 5)

(14, 5) , (21, 3) , (26, 8) , (33, 6) , (38, 11) , (45, 9) , (50 , 5) , (57, 12) , (62, 8) , (69, 15) , (74, 11
