Its indeterminent form... 0/0 can be written as =100–100/100–100 =(10)²–(10)²/10(10–10) =(10+10)(10-10)/10(10–10)→{a²–b² = (a+b)(a–b)} =10+10/10 =20/10 =2

a-d,a,a+d

a-d+a+a+d=21

3a=21

a=7

product=a-d*a*a+=315

multiply them u will get value of d=2

subsitute the value in a-d,a,a+d

numbers are 5,7,9

Gaurav Seth 7 years ago

Let the number be (a-d), a, (a+d)
(a-d)+a+(a+d)=21
a-d+a+a+d=21
3a=21
a=7
(a-d)×a×(a+d)=231
(a²-d²)×7=231
a²-d²=33
7²-d²=33
49-d²=33
d²=49-33
d²=16
d=4
Numbers = 3,7,11
