Pinny is making some patterns of numbers on the board. Can you figure out which patterns are true and false in the following questions: 2, 7, 12, 17, 22,...... B. 10, 20, 30, 40, 50, ...... C. 11, 22, 33, 55, 66,...... D. 3, 6, 9, 13, 15, ......

A) TTFF       

B) TTTF        

C) FFTT                          

D) FTTF

Correct Answer: A

Solution :

    2, 7, 12, 17, 22 Here, the rule is add 5.                           2 + 5 = 7 + 5 = 12 + 5 = 17 and so on. Thus, the pattern is true. B. 10, 20, 30, 40, 50,...... Here, the rule is table of 10. , , and so on. C. 11, 22, 33, 55, 66, ...... Here, the rule is table of 11. , , ,  is missing, thenand so on. Thus, the pattern is false. D. 3, 6, 9, 13, 15....... 3 + 3 = 6 + 3 = 9 = 9 + 3 = 12. But we have 13. Thus, the pattern is false. Therefore, the answer is option (a) TTFF.
