I have soved it in a different way like: 7, 2+6=8, 6+3=9, 1+2+4=7, 2+1+5=8, 3+4+2=9, (4+2+1=7 or 5+1+1=7) so the series is 7,8,9,7,8,9,7 .... Please reply me can we apply this logic here or not |

No. Because here only one answer has taken. Logic is ok. But apply every time. |

I too in same way and that is also the possible way. |

@Bhupinder Singh. Your logic is not working here as the sum of digits of option D (421) is 4+2+1=7, than how we can say the answer is B? |

There is one more way but lengthy: 26 - 7 = 19, 63 - 26 = 37, 124 - 63 = 61, 215 - 124 = 91, 342 - 215 = 127:. If we take the remainders and subtract, 37 - 19 = 18, 61 - 37 = 24, 91 - 61 = 30 127 - 91 = 36 which are multiples of 6, hence the last number should have the difference of 42. Hence 127 + 42 =169. This should be added to 342 to get the answer. |

1 2 9 37 65 126 217 ? Please solve the given series with the correct explanation. |

@Jyoti Yadav. Cube of 0+1=1. Cube of 1+1=2. Cube of 2+1=9. But there is no any cube for 37. Cube of 4+1=65, Cube of 5+1=126. Cube of 6+1=217. That's why 37 is odd in this group. |
