Question

find missing number​

Answer 1

Answer:

30

Step-by-step explanation:

There are two series:

80, 71, 55, _

and

50, 59, 75, 100

The gap between a member of the series and the next is $3^{2} , 4^{2} , 5^{2}$.

80 - 9 = 71

71 - 16 = 55

55 - 25 = 30

The other series

50 + 9 = 59

59 + 16 = 75

75 + 25 = 100
