Q. 18 B5.0( 2 Votes )

# In the following A.P., find the missing terms:54, □,□, 42

Here, a = 54 , n = 4 and l = 42

We have,

l = a + (n – 1)d

42 = 54 + (4 – 1)d

42 = 54 + 3d

–12 = 3d So, the missing terms are –

a2 = a + d = 54 – 4 = 50

a3 = a + 2d = 54 + 2(–4) = 54 – 8 = 46

Hence, the missing terms are 50 and 46
