Answer 2

HEY ^_ ^

GIVEN NUMBER ARE IN A.P. SERIES:-

SO, late here 5 number of AP series:---

a-2d, a-d,a,a+d,a+2d

a/c will be:--

(a-2d,)+( a-d)+(,a,)+(a+d)+(,a+2d)=25.

==>5a=25

==>a=5.

again a/c to question

(a-2d,)^2 +( a-d)^2 +(,a,)^2 +(a+d)^2+(a+2d)^2=135.

put value of a=5.

(5-2d,)^2 +( 5-d)^2 +(,5,)^2 +(5+d)^2+(5+2d)^2=135.

=>125+10d^2 =135

=>10d^2 =10

=>d^2=1

=>d=±1.

find number:-

if, a=5 and d=1

3,4,5,67

if,a=5 and d= -1

7,6,5,4,3
