  1. Mind boggling one :) had to think hard..here goes

    1+2+3=6
    1+4+9=14
    1+8+27=36
    1+16+81=98
    1+32+243=276
    1+64+729=794

    answer=794

  2. 794

    The nth term in the series is given by the sum of x^n for x in the range 1 to 3, i.e. 1^n + 2^n + 3^n.

    Thus the first term is 1^1 + 2^1 + 3^1 = 1 + 2 + 3 = 6,
    the second term is 1^2 + 2^2 + 3^2 = 1 + 4 + 9 = 14,
    and so on.

    The sixth term is then 1^6 + 2^6 + 3^6 = 1 + 64 + 729 = 794.

    2. Jack, your expression in the picture is poorly done, since the summation uses the same symbol, n, as the other terms, which are not subject to the summation.

  3. 8112.
    THE SEQUENCE:
    6= 6
    14= 1 4
    36= 3 6
    98= 9 8
    276= 27 6
    SO, 81 12

  4. another method is :
    14=6*2+2 and this 2 is 6-4. Note down this 4.
    36=14*2+8 and this 8 is 14-6. Note down this 6.
    98=36*2+26 and this 26 is 26-10. Note down this 10.
    276=98*2+80 and this 80 is 98-18. Note down this 18.
    So a series has been formed 4,6,10,18 and hence next number will be 34.
    So the answer will be 276*2+(276-34)=794

  5. Everyone got fooled. That was a trick question. There is no next number. That was the last one

  6. My explaination:

    6 : 1 = 6 >> 6 x 6 = 36 >> third number
    14 : 2 = 7 >> 7 x 14 = 98 >> fourth number

    so, the sisth numbel will be..

    36 : 3 = 12 >> 12 x 36 = 432

  8. 6*2+2=14
    14*2+8=36
    36*2+26=98
    98*2+80=276
    276*2+242=794

  9. every two week is 14 days,every month is more or less 36 days
    evey season is more or less 98 days,every year is more or less 276 so the answer is number of days for 2 years that is more or less 794 days!

    1. If you're so good in math, then perhaps you should spend more time with your English spelling and grammar ...

  12. 6, 14, 36, 98, 276
    14 - 6 - 8 8 x 3 = 24 24 - 2 - 22 22+14 = 36
    36 - 14 - 22 22 x 3 = 66 66 - 4 = 62 62 + 36 = 98
    98 - 36 - 62 62 x 3 = 186 186 - 8 = 178 178 + 98 = 276
    276 - 98 - 178 178 x 3 = 534 534 - 16 = 518 518 + 276 = 794

    1. Wow, that's a really hard one. I'd have to guess ...
      I do know that the prime numbers between 2 and 99, inclusive, are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

  14. (3*2)(7*2)(18*2)(49*2)(138*2)

    (7-3=4)(18-7=11)(49-18=31)(138-48=89)

    (4*3-1)(11*3-2)(31*3-4)(89*3-8=259)
    So the next term will be (138 +259)*2=794
    Hence the sequence will be
    3*2=6,7*2=14,18*2=36,49*2=98,138*2=276,
    397*2=794.

  16. Each number in the series is the sum of 1^n, 2^n, and 3^n, where n is the position in the sequence. Nn = 1^n + 2^n + 3^n.
    The problem would have been harder if the series began with 3.

    1. An alternate solution is:
      Nn=[(n-2)*(n-3)*(n-4)*(n-5)/24]*6
      +[(n-1)*(n-3)*(n-4)*(n-5)/-6]*14
      +[(n-1)*(n-2)*(n-4)*(n-5)/4]*36
      +[(n-1)*(n-2)*(n-3)*(n-5)/-6]*98
      +[(n-1)*(n-2)*(n-3)*(n-4)/24]*276
      For n=6, it yields 696.
