If `a ,b ,a n dc` are in A.P. and `b-a ,c-ba n da` are in G.P., then `a : b : c` is `1:2:3` b.1:3:5 c. `2:3:4` d. `1:2:4`

If 1/a,1/b,1/c are in A.P and a,b -2c, are in G.P where a,b,c are non-zero then

If the angles A,B,C of a triangle are in A.P. and sides a,b,c, are in G.P., then prove that a^2, b^2,c^2 are in A.P.

If 1/(b-a)+1/(b-c)=1/a+1/c , then A. a ,b ,a n dc are in H.P. B. a ,b ,a n dc are in A.P. C. b=a+c D. 3a=b+c

If a,b,c are in H.P,b,c,d are in G.P, and c,d,e are in A.P, then (ab^(2))/((2a-b)^(2)) is equal to

If distinct positive number a , b, c, are in G.P. and (1)/(a-b), (1)/(c-a),(1)/(b-c) are in A.P. , then value of a + ab + c is equal to

Suppose a ,b, and c are in A.P. and a^2, b^2 and c^2 are in G.P. If a

a,b,c are in G.P. and a+b+c=xb, x can not be (a) 2 (b) -2 (c) 3 (d) 4

If a, b, c are in A.P., b, c, d are in G.P. and 1/c ,""1/d ,""1/e are in A.P. prove that a, c, e are in G.P.

If a :(b+c)=1:3 a n d c :(a+b)=5:7, t h e b :(a+c) is equal to 1:2 b. 1:3 c. 2:3 d. 2:1

STATEMENT-1 : If a, b, c are in A.P. , b, c, a are in G.P. then c, a, b are in H.P. STATEMENT-2 : If a_(1) , a_(2) a_(3) ……..a_(100) are in A.P. and a_(3) + a_(98) = 50 " then" a _(1) + a_(2) +a_(3) + ….+ a_(100) = 2500 STATEMENT-3 : If a_(1) , a_(2) , ....... ,a_(n) ne 0 then (a_(1) + a_(2)+ a_(3) + .......+ a_(n))/(n) ge (a_(1) a_(2) .........a_(n) )^(1//n)
