The terms x, x+2, x+4, . . . , x+2n form an arithmetic sequence, with x an integer. If each term of the sequence is cubed, the sum of the cubes is -1197. What is the value of n if n > 3?
a=-11;b=0;c=(a+2)^3;b=b+c ;printb,a,c;if(b==- 1197, goto6, 0); a=a+2;if(a<10, goto2, 0)
OUTPUT: n = 6 and x = - 9
