If the sum of the first 9 terms is 24, then the 4th term of the progression isThe sum of a given infinite geometric progression is 80 and the sum of its first two terms is 35. Then the value of nnn for which the sum of its first nnn terms is closest to 100, isIt is given that the sequence {xnx_nxn} satisfies x1=0,xn+1=xn+1+2√(1+xn)x_1 = 0, x_{n+1} = x_n + 1 + 2√(1+x_n)x1=0,xn+1=xn+1+2√(1+xn) for n=1,2,...n = 1,2,...n=1,2,... Then x31x_{31}x31 is _______
