Fill in the missing numbers to complete each pattern

Question

60 70 65 75 _80 75 _ 80 90

Answer 1

The first missing number is 70

The second missing number is 85

 

 

The odd terms of the sequence counts by 5, but the NEXT number (the even terms) is 10 more.

 

For example, starting with 30, the pattern goes like this

30 40

35 45

40 50

45 55

50 60

55 65

 

Next is the part of the pattern that is shown

60 70

65 75

 

So the next number must be 70.

So it is 70 , then 80.

 

Continuing:

75, then 85

 

FInally

80 90

 

The end shall be:

85 95

90 100

95 105

100 110
