Question

jaldi pura sol do useless ans will be reported​

Answer 1

Step-by-step explanation:

first term of AP is a

and common diff. is D

then,

e = a + 4D

c = a + 2D

d = a +3D

put this values in given eqn.

you will get your ans.

if not, message me i will give you the solution.

Answer 2

Given - a, b, c, d, e and f are in A.P

Let the common difference is x

so.

$Given - a, b, c, d, e and f are in A.PLet the common difference is xso.a + x = b \\ a + 2x = c \\ a + 3x = d \\ a + 4x = e \\ a + 5x = f \\ now \\ e - c = a + 4x - a - 2x \\ e - c = 2x \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: - 1 \\ and \\ d - c = a + 3x - a - 2x \\ d - c = x \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: - 2 \\ from \: 1and \: 2 \: \: we \: get \\ e - c = 2(d - c)$
