-45 plus 512 plus 45 plus 56 = 568
(-9 x -8) + (-16) = (72) -16 = 56
56 + 100 - 24 = 132
85 + 25 - 56 = 54
7 + (7/7) + (7 x 7) - 7 = 50

Answer: 453 The number given can be seen as a sequence of 63 60 56 51. Taking these as separate numbers: 60 is 63 minus 3 56 is 60 minus 4 51 is 56 minus 5 the numbers decrease by the (difference between the last two numbers plus 1) So, 51 minus 6 gives 45 and 45 minus 7 gives 38 The next three numbers are, therefore, 453
45 + 11 = 56
30 + 50 - 56 + 2306 = 2330
56 + 100 - 24 = 132
56 + 82 - 9 = 129
85 + 25 - 56 = 54
It is: 45/56 times 100 = 80.36% rounded to two decimal places
23 + 56 - 4 = 75
