Q18 of 176 Page 8

In the following A.P., find the missing terms:
– 4, □, □, □, 6

Here, a = –4, n = 5 and l = 6

We have,

l = a + (n – 1)d

⇒6 = –4 + (5 – 1)d

⇒6 = –4 + 4d

⇒10 = 4d

So, the missing terms are –

a₂ = a + d

a₃ = a + 2d

a₄ = a + 3d =

Hence, the missing terms are

In the following A.P., find the missing terms:

2, □, 26

In the following A.P., find the missing terms:

□, □, 13, □, □, 22

In the following A.P., find the missing terms:

□, 38, □,□,□, – 22

If 10th term of an A.P. is 52 and 17th term is 20 more than the 13th term, find the A.P.

In the following A.P., find the missing terms:– 4, □, □, □, 6
