Ram Kushwah 6 years, 10 months ago

Let the No. a-d,a and a+d

Sum: a-d+a+a+d=21

3a=21, a=7

product: a(a-d)(a+d)=231

a(a2-d2)=231

7(49-d2)=231

49-d2=33

d²=16, d={tex}\pm{/tex}4

So numbers are:

3,7,11 or 11,7,3

Yogita Ingle 6 years, 10 months ago

Let the AP is (a-d), a, (a+d)
(a-d)+a+(a+d) =21
3a=21
a=7
(a-d)×a×(a+d)=231
(a×a-d×d) ×a=231
(7×7-d×d)×7=231
(7×7-d×d)=231÷7
(7×7-d×d)=33
d×d=49-33
d×d=16
d=4
Hence, the A. P. is 3, 7, 11.
