SBI PO Prelims

Let's identify the pattern in the series: 18, 20, 26, 38, 58, ?

- Start with 18.

- Add 2 to 18, gives us 20.

- Add 6 to 20, which gets 26.

- Add 12 to 26, results in 38.

- Add 20 to 38, leads to 58.

Notice the pattern of adding consecutive factors of 2: (2, 6 = 2x3, 12 = 2x6, 20 = 2x10).

Next step:

- Add 30 to 58 (2x15 = 30).

- Calculation: 58 + 30 = 88

- Therefore, 88 is the number that completes the series.

Highlight Correct Option:

- Option 4: 88
