I hope it will help u.
Answer:
The three terms are 8, 10 and 12
Step-by-step explanation:
the given sum might be about finding the three terms of AP
Given data
sum of three terms in AP = 30
product of three terms = 960
here we need to terms of AP
Let a-d, a and a+2d are be the 3 terms of the AP
sum of three terms = 30
a - d + a + a + d = 30
3a = 30
a = 10
product of 3 terms = 960
(a - d) (a)(a + d) = 960
( a² - d²) (a) = 960
substitute a = 10
(10² - d²)(10) = 960
10² - d² = 96
100 - d² = 96
d² = 4
d = 2
the required three terms are
a - d = 10 - 2 = 8
a = 10
a + d = 10 + 2 = 12
