If `1/(x+2),1/(x+3),1/(x+5)` are in A.P. Then, `x=` (a)5 (b) 3 (c) 1 (d) 2

If 1/(x+2), 1/(x+3) and 1/(x+5) are in A.P. find x

If 1/(x+2),1/(x+3),1/(x+5) are in A.P then the value of x will be a)1 b)2 c)3 d)5

If 1/2+1/x=2, then x= (a) 2/5 (b) 5/2 (c) 3/2 (d) 2/3

If 1/2+1/x=2, then x= 2/5 (b) 5/2 (c) 3/2 (d) 2/3

If x^3-1/(x^3)=14 , then x-1/x=? (a)5 (b) 4 (d) 3 (d) 2

Choose the correct answer in questions 17 to 19: If a, b, c are in A.P., then the determinant [{:(x+2,x+3,x+2a),(x+3,x+4,x+3b),(x+4,x+5,x+2c):}] is : (a) 0 (b) 1 ( c) x (d) 2x

Choose the correct answer in questions 17 to 19: If a, b, c are in A.P., then the determinant [{:(x+2,x+3,x+2a),(x+3,x+4,x+2b),(x+4,x+5,x+2c):}] is : (a) 0 (b) 1 ( c) x (d) 2x

If a,b,c, are in G.P. , a.x.b in A.P. and b,y,c in A.P., then : (a)/(x)+( c )/(y) = (A) 1/2 (B) 1 (C) 2 (D) none of these
