Answer» Step-by-step explanation: SUPPOSE the THREE terms be " a - b, a, a + b " SUM = 24 a-b+a+a+b=24 3a=24 ∴a=8 Product = 480 (a−b)(a)(a+b)=480 (8−b)(8)(8+b)=480 {( we know a=8)} (8−b)(8+b)=60 {we know (a-b)(a+d)=a^2-b^2} 64−b^2=60 b^2=4 b=2 a=8,b=2 a−b=8−2=6, a=8, a+d=8+2=10 terms are 6,8,10. i HOPE its helpful and understand for u Gm have a great day |
