**Answers & Explanations**

1. Answer: (c) 89

**Explanation:**

Here, a_{7} = 34

a_{13} = 64

a_{7} = a + 6d = 34……….(1)

a_{13} = a + 12d = 64…………(2)

Subtracting (1) from (2)

6d = 30

d = 5

Multiplying (1) by 2

2a + 12d = 68………………….(3)

Subtracting (2) from (3)

a = 4

a_{18} = a + (n–1) d

a_{18} = 4 + (17) 5

a_{18} = 89

2. Answer:(d) 28

**Explanation:** For an A.P

\(a_n\) = a + (n – 1)d

4 = a + (7 – 1)( −4)

4 = a + 6(−4)

4 + 24 = a

a = 28

3. Answer: (b) 3.5

**Explanation:** For an A.P

\(a_n\) = a + (n – 1)d

= 3.5 + (101 – 1) × 0

= 3.5

4. Answer: (c) – 2, – 4, – 6, – 8

**Explanation:** Let the first four terms of an A.P are a, a+d, a+2d and a+3d

Given that the first termis −2 and difference is also −2, then the A.P would be:

– 2, (–2–2), [–2 + 2 (–2)], [–2 + 3(–2)]

= –2, –4, –6, –8

5. Answer: (d) n – 2

6. Answer: (c) s – r

7. Answer: (c) Gauss

**Explanation:** Gauss is the famous mathematician associated with finding the sum of the first 100 natural Numbers.

8. Answer: (b) 137

**Explanation:** First two terms are –3 and 4

Therefore,

a = −3

a + d = 4

⇒ d = 4 − a

⇒ d = 4 + 3

⇒ d = 7

Thus,

\(a_{21}\) = a + (21 – 1)d

\(a_{21}\) = –3 + (20)7

\(a_{21}\) = 137

9. Answer: (b) t = p – 4

10. Answer: (b) 33

**Explanation:** Since

\(a_2\) = 13

\(a_5\) = 25

⇒ a + d = 13 ….(i)

⇒ a + 4d = 25 ….(ii)

Solving equations (i) and (ii), we get:

a = 9; d = 4

Therefore,

\(a_7\) = 9 + 6 × 4

\(a_7\) = 9 + 24

\(a_7\) = 33

11. Answer: (c) 25

**Explanation**: Since, d = 5

\(a_{18} – a_{13}\) = a + 17d – a – 12d

= 5d

= 5 × 5

= 25

12. Answer: (c) 17, 21

**Explanation:** Here, a = −11

d = − 7 – (−11) = 4

And \(a_n\) = 49

We have,

\(a_n\) = a + (n – 1)d

⇒ 49 = −11 + (n – 1)4

⇒ 60 = (n – 1)4

⇒ n = 16

As n is an even number, there will be two middle terms which are 16/2th and [(16/2)+1]th, i.e. the 8th term and the 9th term.

\(a_8\) = a + 7d = – 11 + 7 × 4 = 17

\(a_9\) = a + 8d = – 11 + 8 × 4 = 21

13. Answer: (a) 4

**Explanation:** For an AP,

\(a_n\) = a+(n-1)d

= 28+(7-1)(-4)

= 28+6(-4)

= 28-24

\(a_n=4\)

14. Answer: (b)10,20,30,40

**Explanation:** a = 10, d = 10

\(a_1\) = a = 10

\(a_2 = a_1+d\) = 10+10 = 20

\(a_3 = a_2+d\) = 20+10 = 30

\(a_4 = a_3+d\) = 30+10 = 40

15. Answer: (c) 3 and -2

**Explanation:** First term, a = 3

Common difference, d = Second term – First term

⇒ 1 – 3 = -2

⇒ d = -2

16. Answer: (a) 1

**Explanation:** \(N^{th}\) term in AP is:

\(a_n\) = a+(n-1)d

\(a_{17}\) = a+(17−1)d

\(a_{17}\) = a +16d

In the same way,

\(a_{10}\) = a+9d

Given,

\(a_{17} − a_{10} = 7\)

Therefore,

(a +16d)−(a+9d) = 7

7d = 7

d = 1

Therefore, the common difference is 1.

17. Answer: (d) 4

**Explanation:** Here, \(S_n= 3n^2 + n\)

d = 6

Putting n= 1

\(S_1\) = 3 + 1 = 4

Sum of first 1 term = first term = 4

18. Answer: (c) 4n + 3

**Explanation:** Here S_{n }= 2n^{2} + 5n

Sum of the A.P with 1 term = S_{1} = 2 + 5 = 7 = first term

Sum of the A.P with 2 terms = 8 + 10 = 18

Sum of the A.P with 3 terms = 18 + 15 = 33

a_{2} = S_{2} – S_{1} = 18 – 7 = 11

d = a_{2} –a_{1} = 11 – 7 = 4

n^{th} term = a + (n–1) d

= 7 + (n–1) 4

n^{th} term = 4n + 3

19. Answer: (c) 21

**Explanation:** Let 3 consecutive terms A.P is a –d, a, a + d. and the sum is 51

So, (a –d) + a + (a + d) = 51

3a –d + d = 51

3a = 51

a = 17

The product of first and third terms = 273

So, (a –d) (a + d) = 273

a^{2} –d^{2} = 273

17^{2} –d^{2} = 273

289 –d^{2} = 273

d^{2} = 289 –273

d^{2} = 16

d = 4

Third term = a + d = 17 + 4 = 21

20. Answer: (c) 60

**Explanation:** The multiples of 4 after 10 are:

12, 16, 20, 24, …

So here, a = 12 and d = 4

Now, 250/4 gives remainder 2. Hence, 250 – 2 = 248 is divisible by 2.

12, 16, 20, 24, …, 248

So, nth term, an = 248

As we know,

an = a+(n−1)d

248 = 12+(n-1)×4

236/4 = n-1

59 = n-1

n = 60
