Question

If a, b, c, d, e are in ap find the values ofa-4d+6c-4d+e

Answer 1

Answer:

Step-by-step explanation:

let say x is difference of ap

then

b = a+x

c = a + 2x

d = a + 3x  

e = a + 4x

a - 4d + 6c - 4d + e

= a - 4a - 12x + 6a + 12x - 4a - 12x + a + 4x

=  -8x

= -8(b-a)

= 8(a-b)

loos like question should be

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

= a - 4a - 4x + 6a + 12x - 4a - 12x + a + 4x

=  4a
