Answer:
97
Step-by-step explanation:
(3+1) - (7-5) = 2
(8+1) - (8-3) = 4
(7+2) - (9-8) = 8
so the series is 2,4,8,.... thus going by the series the next number in this series should be 16
Let a,b be the two digits of the number.
(a+b) - (7-7) = 16
a+b = 16.
Thus the values of a and b which can result in sum being 16 are
97, 79 or 88.
Thus 97 is the missing number.
