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

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))=110, then x+(1)/(x)=5 (b) 10 (c) 15 (d) none of these

If a and b are distinct positive real numbers such that a, a_(1), a_(2), a_(3), a_(4), a_(5), b are in A.P. , a, b_(1), b_(2), b_(3), b_(4), b_(5), b are in G.P. and a, c_(1), c_(2), c_(3), c_(4), c_(5), b are in H.P., then the roots of a_(3)x^(2)+b_(3)x+c_(3)=0 are

If 2x+1,x^(2)+x+1 and 3x^(2)-3x+3 are in A.P ,then the value of x :

If x_(1),x_(2),x_(3),"……" are in A.P., then the value of 1/(x_(1)x_(2))+1/(x_(2)x_(3))+1/(x_(3)x_(4))+"……"1/(x_(n-1)x_(n)) is :

If x+2 is a factor of x^2+a x+2b and a+b=4 , then (a) a=1, b=3 (b) a=3, b=1 (c) a=-1, b=5 (d) a=5, b=-1
