Question

I need a solution to this quantitative aptitude problem
​

Answer 1

Explanation:

Not sure about this but it looks like we subtract 1 from the first number then add 3 times the difference in the example (N) to get each subsequent number so the Z part is in 1:

10-1 = 9 and second value is 9 + 3*(15-10) = 24 and third is 24 * 3*18 = 78 and so on.

So 1 is:

9 24 78 141

The others are worked out in the same way:

so 2 is

5 44 107 173
