    Explanation:

    - Given series: 15, 30, 44, 57, 69, ?

    - Check differences between terms:

    - 30−15=15

    - 44−30=14

    - 57−44=13

    - 69−57=12

    - Identified pattern: Differences decrease sequentially by 1.

    - Calculate next difference:

    - Next should decrease by 1 from 12, so it is 11.

    - Find missing number:

    - 69+11=80

    - Options:

    1. 80

    2. 91

    3. 78

    4. 85

    - Correct Answer: Option 1 - 80
