To solve a mathematical puzzle, observe the puzzle and try to solve it to find the solution to the problem. If you cannot find the solution, we have an answer for you. If you are still working to figure it out, we have the solution to this mathematical puzzle. This puzzle will allow you to see how keen you are and how reasonable an observer you are. If you still need help, the picture below will help you understand the solution.
9 4 3 12 37 84
1st difference: -5 -1 9 25 47
2nd difference: 4 10 16 22
3rd difference: 6 6 6 6
Explanation:
From the pattern above, note that after extracting the 3rd difference we get a uniform difference of 6. If we wish to get the fifth number of the sequence of the 2nd difference, we will just add 6 with the last given number in the sequence which is 22. Thus 22 + 6 = 28.
To get the next number on the sequence for the 1st difference, we will add 47 which is the last given number of the sequence with 28 which is the 5th term of the sequence on the 2nd difference. Thus, 47 + 28 = 75.
Lastly, to get the next number of the original sequence, we will just add 75 with 84 which is the given last term of the sequence. Thus, 84 + 75 = 159.
So the answer is 159.
