[" Q."17." For A.P.show that "a_(p)+a_(p+2q)=2a_(p+q)],[qquad [" A [Board Term- "2,2012]]

For any AP show that a_(p)+a_(p+2q)=2a_(p+q)

For an A.P., show that T_p+T_(p+2q)=2T_(p+q) .

In AP a_(p) = q, a_(q) = p then a_(p+q) = ………….

Show that: x p q p x q q q xx-p)(x^2+p x-2q^2) .

If a_(1),a_(2),a_(3),…. are in A.P., then a_(p),a_(q),a_(r) are in A.P. if p,q,r are in

If ‘a’ and ‘b’ are respectively the pth and qth terms of an A.P., show that the sum of (p + q) terms is (p+q)/2[(a + b) + (a- b)/(p - q)] .

Show that: |x p q p x q q q x|=(x-p)(x^2+p x-2q^2)dot

If a_(1),a_(2),a_(3),…. are in A.P., then a_(p),a_(q),q_(r) are in A.P. if p,q,r are in

If a_(1),a_(2),a_(3),…. are in A.P., then a_(p),a_(q),q_(r) are in A.P. if p,q,r are in
