Help Jacob find the next two numbers of the given series.

8, 6, 9, 23, 87, __, ___ .

• A. 429 and 2576
• B. 2567 and 429
• C. 2576 and 429
• D. 429 and 2567

Answer 1

The correct option is D 429 and 2567

The series follows the given pattern:

First term: 8
Second term: 8 × 1 – (1 + 1) = 6
Third term: 6 × 2 – (2 + 1) = 9
Fourth term: 9 × 3 – (3 + 1) = 23
Fifth term: 23 × 4 – (4 + 1) = 87
Sixth term: 87 × 5 – (5 + 1) = 429
Seventh term: 429 × 6 – (6 + 1) = 2567

So, the missing numbers of the series are 429 and 2567.
