    Pinny is making some patterns of numbers on the board. Can you figure out which patterns are true and false in the following questions: A. 1, 2, 3, 3, 2, 1, 1, 2, 3....... B. 2, 2, 4, 4, 6, 6, 6, 8, 8,...... C. 1, 1, 0, 2, 2, 0, 3, 3, 3,...... D. 2, 4, 6, 8, 10, ......

    A) TTFF                          

    B) TFTF        

    C) TFFT     

    D) FFTT

    Correct Answer: C

    Solution :

        1, 2, 3, 3, 2, 1, 1, 2, 3 Here, the sequence 1, 2, 3 is being repeated first in the same order then in the opposite order of numbers. This pattern is true. B. 2, 2, 4, 4, 6, 6, 6, 8, 8 In this pattern even numbers are occurring two times but 6 is occurring three times. Thus, this pattern is false. C. 1, 1, 0, 2, 2, 0, 3, 3 In this pattern, the rule is number will occur two times followed by 0. But here 3 is occurring 3 times. Thus, this pattern is false. D. 2, 4, 6, 8, 110 In this pattern, the rule is even numbers. Thus, the pattern is true. Therefore, the answer is option (c) TFFT.
