four numbers are in Ap the sum of externs is 10 and the product of the means is 24 find the namber About the author Eliza
Answer: first term = 5 common difference = 1 Explanation: let the numbers in the AP as a-3d, a-d, a+d, a+3d According to the question, (a-3d)+(a+3d) = 10 →2a = 10 →a= 10/2 = 5 →(1) and (a-d)(a+d) = 24 →a²-d² = 24 from (1) we get 5²-d² = 24 →d² = 25-24 →d = √1 = 1 Step-by-step explanation: Reply
Answer:
first term = 5
common difference = 1
Explanation:
let the numbers in the AP as a-3d, a-d, a+d, a+3d
According to the question,
(a-3d)+(a+3d) = 10
→2a = 10
→a= 10/2 = 5 →(1)
and (a-d)(a+d) = 24
→a²-d² = 24
from (1) we get 5²-d² = 24
→d² = 25-24
→d = √1 = 1
Step-by-step explanation:
