    Question

    Select the numbers from among the given options that can replace the question marks (?) in the following series.
    213, 216, 221, 228, 237, (?), 261, (?)

    A.

    248, 276

    B.

    259, 286

    C.

    247, 275

    D.

    246, 277

    Correct option is A

    Given: 213, 216, 221, 228, 237, (?), 261, (?)
    Logic: Add consecutive odd numbers (starting from 3) to each term to get the next term in the series.
    213 + 3 = 216; 216 + 5 = 221; 221 + 7 = 228; 228 + 9 = 237
    Similarly, 237 + 11 = 248
    248 + 13 = 261
    Also, 261 + 15 = 276
    So, 248, and 276 are the missing terms of the given series.
    Thus, the correct answer is (a).
