1. Pattern in figure 1,

        15 = (2 + 3) * 3

        In figure 2,

        45 = (4 + 5) * 5

        Therefore, in figure 3,

        ? = (3 + 6) * 6

         = (9) * 6

        = 54

2. According to this code:

    A = 2, M = 3, N = 7, P = 4, I = 1 ……

    Hence, AIM can be written as: 213

 

3.     The first term is 6. The second term is 6 * 4/1 = 24 . The third term is 24 * 5/2 = 60. The fourth term     is 60 * 6/3 = 120 . So, the fifth term is 120 * 7/4 = 210

4.  Corrected Sentence: I don’t know anything about it.

 

5. We can observe that the following numbers are there in the series:

    2 * 3 = 6

    4 * 5 = 20

    6 * 7 = 42

    8 * 9 = 72

    10 * 11 = 110

    12 * 13 = 152

    14 * 15 = 210 (ANSWER)

    16 * 17 = 272

    18 * 19 = 342
