If `a, b, c` are in `A.P.,` and `Delta=|[x+2,x+7,a],[x+5,x+11,b],[x+8,x+15,c]|` then `Delta` equals to

If a,b,c are in A.P., and x+2,x+7,ax+5,x+11,bx+8,x+15,c]| then Delta equals to

If a, b, c are in A.P., then |{:(x+2,x+3,x+a),(x+4, x+5, x+b),(x+6, x+7,x+c):}| is

If a,b,c are in A.P., then the determinant |[x+2, x+3, x+2a],[x+3,x+4,x+2b],[x+4,x+5,x+2c]| is

If a, b, c, are in A.P, then the determinant |[x+2,x+3,x+2a],[x+3,x+4,x+2b],[x+4,x+5,x+2c]| is:

if a,b,c are in A.P. show that : | [ x+1, x+2,x+a],[x+2,x+3,x+b],[x+3,x+4,x+c ] |=0

If a, b , c are in A.P show that |[x+1, x+2, x+a],[ x+2, x+3, x+b],[ x+3, x+4, x+c]|=0

If a, b, c, are in A.P, then the determinant |[x+2,x+3,x+2a], [x+3,x+4,x+2b], [x+4,x+5,x+2c]| is(A) 0 (B) 1 (C) x (D) 2x

If a,b,c are in A.P., show that : |(x+1,x+2,x+a),(x+2,x+3,x+b),(x+3,x+4,x+c)|=0

If a,b,c, are in A.P. then |(x+1,x+2,x+a),(x+2,x+3,x+b),(x+3,x+4,x+c)|=

if a, b,c are in A.P. then what is the value of: |[x+1,x+2,x+a],[x+2,x+3,x+b],[x+3,x+4,x+c]| ?
