I think you mean 36 not 38 since\n\n4 = 4*3^0\n12 = 4*3^1\n36 = 4*3^2\n108 = 4*3^3\n324 = 4*3^4\n\nSo, if that's the case, it's 324.\n\nUPDATE: Kemmy, 1^3+1 = 2, not 4.

For five consecutive, there are 34 possibilities because you could start with 1, 2, 3,..., or 34\nYou can't start with 35 because then you would have\n35, 36, 37, 38 which is only four numbers.\nI'm not sure about the other two.\nNote: The answer to the other two are not 35 and 36.

The numbers give the next in the sequence, for example 3692 is 369*2 and that is 738 and so on.\n\n369 x 2 = 738 || 73 x 8 = 584 || 58 x 4 = 232 || 23 x 2 = 46\n\nYour final answer is 46.

I will explain a method that is the most easy on this planet, and a unique one.\n\nI will illustrate with the help of a simple example.\n\nEg. 4-2.\n\nDraw no. line as follows:\n\n<-6--5--4--3--2--1--0--1--2--3--4--5--6--7-->\n\nNumbers left to zero are negative integers\nand to the right are the positive ones.\n\nLocate 4 on this line. Now move 2 steps behind 4 as the operation to be carried out is subtraction.\n\nThis will give answer as 2. \n\nSimilarly for addition move the steps ahead.

in geometric sequence \nUn = U1[r^(n-1)]  \nwhere,\nU1 = first term\nr = common ratio\nn = number of terms\n\nthen we can say that,\nU4 = U1[r^(4-1)]\n24 = U1[r^3]    -> let this be equation (1)\nand\nU7 = U1[r^(7-1)]\n192 = U1[r^6]   -> let this be equation (2)\n\nif you divide equation (1) by equation (2), you'll get\n\n(24/192) = U1[r^3] / U1[r^6]\n(1/8) = 1/r^3\ntherefore \nr = 2\nif r=2 then you can get U1 by substituting r in equation (1)\n\n24 = U1[r^3]\nU1 = 24/8\nU1 = 3\n\ntherefore,\n\nUn = 3[2^(n-1)]

this one is pretty easy\nafter 46 i will give u the next no.\n\n54,55,62,63,69,70,75,76\n\nc it goes like that 80,81,84,85,....

What is the relationship between the items in the sequence? If you are adding the same thing over and over, it is arithmetic (2,4,6,8,10). If you are multiplying by the same thing over and over, it is geometric (2,4,8,16,32).

4 to the 3rd is 4 multiplied by itself 3 times\n\n4 to the 3rd = 4 x 4 x 4\n\n2 to the 6th = 2 x 2 x 2 x 2 x 2 x 2
