यदि a,b,c A.P. में हैं तो दिखाइये कि 2(a - b) = a - c = 2( b - c)

(i) a , b, c are in H.P. , show that (b + a)/(b -a) + (b + c)/(b - c) = 2 (ii) If a^(2), b^(2), c^(2) are A.P. then b + c , c + a , a + b are in H.P. .

(i) a , b, c are in H.P. , show that (b + a)/(b -a) + (b + c)/(b - c) = 2 (ii) If a^(2), b^(2), c^(2) are A.P. then b + c , c + a , a + b are in H.P. .

If a^2 + b^2 + c^2 = 2(a -b -c)- 3 ,then the value of (a- b + c) is यदि a^2 + b^2 + c^2 = 2(a -b -c)- 3 तो (a- b + c) का मान है-

If a, b, and c are in A.P then (a + 2b -c) . ( 2b +c-a) . (c+a-b) = ............. .

If a, b, c are in A.P., then show that (i) b + c – a, c + a – b, a + b – c are in A.P.

If l n(a+c),l n(a-c)a n dl n(a-2b+c) are in A.P., then (a) a ,b ,c are in A.P. (b) a^2,b^2, c^2, are in A.P. (c) a ,b ,c are in G.P. d. (d) a ,b ,c are in H.P.

If l n(a+c),l n(a-c)a n dl n(a-2b+c) are in A.P., then (a) a ,b ,c are in A.P. (b) a^2,b^2, c^2, are in A.P. (c) a ,b ,c are in G.P. d. (d) a ,b ,c are in H.P.

If a, b, c are in A.P, then show that: \ b c-a^2,\ c a-b^2,\ a b-c^2 are in A.P.
