a  small mistake in last fifth line it is

d>30-3d        sorry for that

 Discussion Forums -> This Post 15 points    (3    in 3 votes )   [?]

this quest requires some concept of function chapter

let the no be

A-d,   A,   A+d,  b    (in increasing order)

as given    b-(A-d)=30

b=30+A-d        now numbers

A-d,  A, A+d,  30+A-d

apply gm formula

A*(30+A-d)=(A+d)^2

........after solving u will get

,   as  A>0    then

10-d>0.......,     10>d

and all terms are postive thus d>0 and it must be divisible by 3 because A is a integer

so we have options for d   ------ 3,    6,    9

but     A-d>0    (all terms are +VE)

A>d,

d>30-d   ,    d>7.5

so  finally we will take d=9  and   then

A=27           numbers are

18  ,27  ,36,  48

their sum  =129

my answer is right because you didnt mentioned about common difference to be a positive integer .thus i considere a c.d. a positive real number

which is equal to  0.00000..........................................01

which is very small value

is there anyone other than ronnie who says i m wrong

i forgot to write in few places so sorry for that

i dont know i m right or wrong

if we have to consider minimum postitive common difference then

c.d.=

it is such a small quantity such that

so  a1+a5+a10+a15+a19+a24=225

6 *(a1)=225

a1=225/6

and sum of 24 terms

a1+a2+a3+...........+a24

=24*(a1)

=24*225/6

=900

i dont know i m right or wrong

alpha=A   and beta=B

if  A and B are roots of a quadratic eq then quadratic eq is given by

(x-A)(x-B)=0

x^2  -(A+B)x  +AB=0

comparing it with our given eq we get

A+B=1   and   AB=1     now

question is this

$\hspace{-16}If \mathbf{a>b>c} and \mathbf{a,b,c} are the Roots of the equation\\\\ \mathbf{x^3-2x^2-x+1=0}\;.Then value of \mathbf{a^2b+b^2c+c^2a=}$
