The common difference of the A.P. `1/(2b),(1-6b)/(2b),(1-12 b)/(2b),...` is `2b` (b) `-2b` (c) `3` (d) `-3`

The common difference of the A.P. 1/(2b), (1-6b)/(2b), (1-2b)/(2b) is………………

The common difference of the A.P. 1/(2b),(1-6b)/(2b),(1-12 b)/(2b),... is (a) 2b (b) -2b (c) 3 (d) -3

The common difference of the A.P. 1/3,(1-3b)/3,(1-6b)/3,\ dot is 1/3 (b) -1/3 (c) b (d) b

The common difference of the A.P. 1/3,(1-3b)/3,(1-6b)/3,\ dot is (a) 1/3 (b) -1/3 (c) - b (d) b

If a^(2),b^(2),c^(2) are in A.P.,then prove that the following are also in A.P.(i) (1)/(b+c),(1)/(c+a),(1)/(a+b) (ii) (a)/(b+c),(b)/(c+a),(c)/(a+b)

If a,b,c are in G.P., show that 1/(a+b),1/(2b),1/(b+c) are in A.P.

Find out which of the following sequences are A.P. for those which are A.P., find out the common difference. ,- a + b, (a + 1) + b, (a + 1) + (b + 1), (a+ 2) + (b + 1), (a + 2) + {b + 2), ....

If a,b,c are in G.P. then prove that (1)/(a+b),(1)/(2b),(1)/(b+c) are also in A.P.
