Question
Given, a8 + a4 = 24 and a10 + a6 = 44
a8 = a + 7d
a4 = a + 3d
As per question;
a + 7d + a + 3d = 24
Or, 2a + 10d = 24
Or, a + 5d = 12 …………(1)
a10 = a + 9d
a + 9d + a + 5d = 44
2a + 14d = 44
a + 7d = 22 (2)
Subtracting equation (1) from equation (2);
a + 7d – a – 5d = 22 – 12
2d = 10
d = 5
solved
