`1/4, (-1)/4, (-3)/4, (-5)/(4)`, d = ……….

For the AP: 1/4, (-1)/4, (-3)/4,(-5)/5 , .........., write the first term a and the common difference d. And find teh 7^(th) term.

What should be added to (-5)/(4) to get -1 ? A. (-1)/(4), B. (1)/(4), C. 1, D. (-3)/(4)

5(1)/(6)-3(1)/(4)+3(1)/(3)+4

What should be subtracted from (-5)/(4) to get -1? (a) (-1)/(4) (b) (1)/(4) (c) 1 (d) (-3)/(4)

If XxxY = {(1, 2),(4, 3), (5, 2),(1, 4),(4, 2), (5, 4),(1, 3),(4, 4),(5, 3)}, find X and Y.

(7(1)/(2)-5(3)/(4))/(3(1)/(2)+?)-:((1)/(2)+1(1)/(4))/(1(1)/(5)+3(1)/(2))=0.6 a) 4(1)/(3)(b)4(1)/(2) (c) 4(2)/(3) (d) None of these

If 4 + (4 +d)/( 5) + (4 + 2d)/(5 ^(2)) ……….=1, then find d.

It is given that (1)/( 1^(4) ) + ( 1)/( 2^(4)) + ( 1)/( 3^(4)) +"......" to oo = ( pi^(4))/( 90) , then (1)/( 1^(4)) +( 1)/( 3^(4)) +( 1)/( 5^(4)) + "......" to oo is :
