In an A.P sum of three number in A.P is 24 product is 480 write three terms of an A.P

Question

Clara · Answer

Answer:   Let the three terms be a - d, a, a + d  Sum = 24                  Product = 480  ∴a−d+a+a+d=24  3a=24  ∴a=8  (a−d)(a)(a+d)=480  (8−d)(8)(8+d)=480[∵a=8]  (8−d)(8+d)=60  64−d2=60  d2=±4=±2  If a=8,d=2 the terms are   a−d=8−2=6,a=8,a+d=8+2=10  ∴ the term are 6,8,10.    We will get the same values if we'll consider d=−2.
