A. 105
B. 424
C. 34
D. 2124
Feedback The following pattern has been followed in this question:
16 = 15 x 1 + 1
34 = 16 x 2 + 2
We have established that previous number is multiplied by increasing numbers (1,2,3,4.....) and then added by increasing numbers (1,2,3,4...)
105 = 34 x 3 + 3
424 = 105 x 4 + 4
2125 = 424 x 5 + 5
2124 is incorrect
