Answer 1

Answer:

7,16,25

Step-by-step explanation:

Let the terms of an AP be a - d, a, a + d.

(i) Sum:

a - d + a + a + d = 48

3a = 48

a = 16.

(ii) Product:

(a - d) * a = 4(a + d) + 12

(16 - d) * 16 = 4(16 + d) + 12

256 - 16d = 64 + 4d + 12

256 - 16d - 64 - 4d - 12 = 0

180 - 20d = 0

180 = 20d

d = 9.

Then:

a - d = 7

a = 16

a + d = 25

Therefore, the AP is 7,16,25.

Hope it helps!
