A) 188 | B) 256 |

C) 240 | D) 180 |

Explanation:

The pattern is x1+3, x 2, x1+3, x 3, x1+3, x 4

The next number=60x4=240

A) 80 | B) 78 |

C) 72 | D) 70 |

Explanation:

The pattern is 2x32=64, 3x24=72, 4x19=76

The next number = 5x15.6=78

A) 18 | B) 5 |

C) 59 | D) 32 |

Explanation:

In the given series,

2nd term = 1st term + =4 +1 = 5

3rd term = 2nd term + =5+4= 9

4th term = 3rd term + =9+9=18

5th term = 4th term + = 18+16=34

odd term is 32

A) 228 | B) 542 |

C) 232 | D) 415 |

Explanation:

Here 2nd number = 1st number 1 +1

3rd number = 2nd number 2 +2

4th number = 3rd number 3 +3 and so on..

5th number = 4th number 4 +4 =57 4 + 4 =232.

A) 104 | B) 48 |

C) 22 | D) 216 |

Explanation:

In the given series,

2nd term =

3rd term =

and so on...

Here 6th term =

22 is wrong.

A) 15U21 | B) 15R18 |

C) 15S19 | D) 15T20 |

Explanation:

In the given series

1st term has odd number starting from 11, So the Series is 11, 13, 15, 17, 19

2nd term has an alphabet follwed by its alpha numeric number in the order +4, +3, +2, +1. So the Series is M13, Q17, T20, V22, W23

15T20 is the answer.
