Which of the following numbers will replace the question mark (?) in the given series?
589, 588, 583, ?, 433, -192
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 558.
Given series: 589, 588, 583, ?, 433, -192
The series follows this pattern:
589 - 1 = 588
588 - (1 × 5) = 588 - 5 = 583
583 - (5 × 5) = 583 - 25 = 558
558 - (25 × 5) = 558 - 125 = 433
433 - (125 × 5) = 433 - 625 = -192
So, the missing term in the series is 558.
