S = 10 + r
s + r = 100
Adding equations,
2s +r = 110 + r
2s = 110
s = 55
r = 45

Answer:
The correct option is A
The missing number is 34
Explanation:
By inspection, the third number is obtained by adding the two preceding numbers.
1 + 1 = 2
The next number is obtained by adding the two preceding numbers.
2 + 1 = 3
This continues as:
3 + 2 = 5
8 + 5 = 13
13 + 8 = 21
21 + 13 = 34
