Question

Please answer these maths class 10th AP ques...

Answer 1

a , b ,c ,d ,e in AP

let first term is a and common difference is d .

then ,
first term = a

2nd term = b = a+d

3rd term = c = a+2d

4th term = d = a+3d

5th term = e = a+4d

now ,

=> a - 4b + 6c -4d+e

= a - 4( a+d ) + 6(a+2d) - 4(a+3d) + a+4d

= a -4a - 4d + 6a + 12d - 4a -12d + a + 4d

= 0
