Are you looking for a set of 8 consecutive whole numbers that when you add 7 of them together in different combinations you receive those 3-digit responses?\n\nWell you've only listed 6 possibilities and only one of those is odd.\n\nStarting at 29 the lowest combination is 224 and the highest is 231.  Starting at 28 the lowest is 217.

take the last digit of the number and multiply by the earlier digits to get the next answer\n369*2= 738\n73*8=584\n58*4=232\ntherefore next number will be 23*2=46

Well let's say the page to which she opened is n.  The seventh page after that is n+7, then n+14, then n+21, all the way up to n+140.  When you add all the n's together, you get 21n, and then there's the sequence of 20 multiples of 7.  So you have:\n21n + 7 + 14 + 21 + ... +140\nSimplified, this is 21n + 1470\nYou know the sum is 1995, so 21n + 1470 = 1995\nSubtract 1470 from both sides, then divide both sides by 21, and you get n = 25.

the successive differences are -6 , -7 , -8 \n\nso next number is =-25

1 + (18-7n) = -9\nCombine 1 and 18\n19 - 7n = -9\nSubtract 19 from each side\n-7n = -28\nDivide both sides by -7\nn = -28/-7\nReduce\nn = 4

2+7\n3+6\n9+0\n\nThat's it. They all add up to 9... I think that's what the question is asking.

I think you mean 56 thousandths with the "th" in it... then that would be .056 otherwise it is 56,000.\n\nHope I helped!

Use distribution to simplify...\n\n6f + 27 = -7 + f\n\nNow isolate the variable and solve.

The first number has to be (x+6) and the second number is (x).  There are four possible combinations: 6,0 (60); 7,1 (71); 8,2 (82); 9,3 (93).  60 plus 8 (68) does not equal 06, or 6.  71 plus 8 does not equal 17.  82 plus 8 does not equal 28.  93 plus 8 does not equal 39.\nUnfortunately, this problem is impossible.\nSorry I couldn't be of more help.

It's multiple choice, so all you really need to do is start plugging numbers in and see if they work:\ng(7) = 2(343) -11(49) + 8(7) + 21\ng(7) = 686 - 539 + 56 + 21 =/= 0\n\ng(1) = 2(1) - 11(1) + 8(1) + 21\ng(1) = 2 - 11 + 8 + 21 =/= 0\n\ng(7/2) = 2(343/8) - 11(49/4) + 8(7/2) + 21\ng(7/2) = 343/4 - 539/4 + 112/4 + 84/4 = 0\n\nThus, d is the right answer.
