Hi Shruti!So, the pattern is as follows:Here we are given the function that depicts the smallest integer greater than or equal to x.Now, [sqrt(1)] = [1] = 1 since it is an integerNow, [sqrt(2)] = [1.414] = 2[sqrt(3)] = [1.732] = 2[sqrt(4)] = [2] = 2[sqrt(5)] = [2.2] = 3So, the value of this function changes just after the number inside the square root becomes perfect square.So, the value will be: 1 + 2 * 3 + 3 * 5 + 4 * 7 + 5 * 9 + 6 * 11 + 7 * 13 + 8 Thus, the value is 260

in this question I'm not able to identify the pattern properly i referred the solution but still i didnt understood image.png 27.58 KB
