Series!!

1. Write the arithmetic series for the given sequence 5, 10, 15, 20, 25, ….., x_n.

Solution:

Given sequence: 5, 10, 15, 20, 25, ……, x_n.

Therefore, the arithmetic series for the given sequence is 5 + 10 + 15 + 20 + 25 + …… + x_n.

2. Write the formula for arithmetic and geometric series.

Solution:

As we know, the arithmetic sequence is of the form: a, a + d, a + 2d, a + 3d, …

Hence, the formula for arithmetic series is a + (a + d) + (a + 2d) + (a + 3d) + …

Similarly, the geometric sequence is of the form: a, ar, ar²,…., ar^(n-1),…

Hence, the formula for geometric series is a + ar + ar² + …+ ar^(n-1)+ …

3. Find the missing number in the given series 13, 24, 46, 90, 178, ?.

Solution:

Given series: 13, 24, 46, 90, 178, ?.

24 – 13 = 11

46 – 24 = 22

90 – 46 = 44

178 – 90 = 88

The logic used here is that the difference between two successive numbers is doubled consecutively.

So, if 88 is doubled, we get 176.

Hence, 178 + 176 = 354.

Thus, the missing term in the sequence is 354.

Therefore, the complete series is 13, 24, 46, 90, 178, 354.

4. Find the missing number in the given series 4, 18, ___, 100, 180, 294, 448.

Solution:

The given sequence is obtained as follows:

2³ – 2² = 8 – 4 = 4

3³ – 3² = 27 – 9 = 18

4³ – 4² = 64 – 16 = 48

5³ – 5² = 125 – 25 = 100

6³ – 6² = 216 – 36 = 180

7³ – 7² = 343 – 49 = 294

8³ – 8² = 512 – 64 = 448

Hence, the missing number in the series is 48.

Therefore, the complete series is 4, 18, 48, 100, 180, 294, 448.

5. Determine the missing numbers in the series 5, 6, 9, 14, 21, ?.

Solution:

Given the number series: 5, 6, 9, 14, 21, ?.

5 + 1 = 6

6 + 3 = 9

9 + 5 = 14

14 + 7 = 21

21 + 9 = 30.

Hence, the missing number here is 30.

Here, the series follows a pattern of the sum of consecutive odd numbers.

So, the complete number series is 5, 6, 9, 14, 21, 30.

6. Complete the series 1, 2, 10, 37, 101, __.

Solution:

Given series: 1, 2, 10, 37, 101, ___.

1 + 1³ = 1 + 1 = 2

2 + 2³ = 2 + 8 = 10

10 + 3³ = 10 + 27 = 37

37 + 4³ = 37 + 64 = 101

101 + 5³ = 101+ 125 = 226

Thus, the given series follows a pattern of the sum of cubes of the consecutive natural numbers.

So, the complete series 1, 2, 10, 37, 101, 226.

7. Find out the wrong term in the given series: 2, 3, 12, 37, 86, 166, 288.

Solution:

Given series: 2, 3, 12, 37, 86, 166, 288.

2 + 1² = 2 + 1 = 3

3 + 3² = 3 + 9 = 12

12 + 5² = 12 + 25 = 37

37 + 7² = 37 + 49 = 86

86 + 9² = 86 + 81 = 167

167 + 11² = 167 + 121 = 288.

Here, the series follows a pattern of addition of the square of the consecutive odd numbers.

So, from the given number series 2, 3, 12, 37, 86, 166, 288, the wrong term is 166, because it should be 167.

8. Find the missing number 25: 37:: 49:?

Solution:

Here, 5² = 25 and (5+1)² + 1 = 37

Similarly, 7² = 49 and (7+1)² + 1 = 65.

Hence, the missing number is 65.

9. 11 : 121 :: 13 : ____. Find the missing value.

Solution:

Here, 11² = 121

So, 13²= 169

So, the missing number is 169.

I.e., 11: 121 :: 13 : 169.

10. Find out the missing term in the given series: 11, 17, 39, 85, ?.

Solution:

Given series: 11, 17, 39, 85, ?.

11 + (3² – 3) = 11 + 6 = 17

17 + (5² – 3) = 17 + 22 = 39

39 + (7² – 3) = 39 + 46 = 85

85 + (9² – 3) = 85 + 78 = 163

Therefore, the missing number in the given series is 163.

I.e., 11, 17, 39, 85, 163.
