Which of the following numbers will replace the question mark (?) in the given series?
13, 78, 83, ?, 335, 670
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 332
Given series: 13, 78, 83, ?, 335, 670
Logic used here is:
13 x 6 = 78; 78 + 5 = 83
335 x (6 - 4) = 670
So, 83 x (6 - 2) = 83 x 4 = 332; 332 + (5 - 2) = 332 + 3 = 335
Hence, option 2 is the correct option.
