1 The sequence 1,4,9,16, 25…… is an example of cube numbers. (True/False)

2 A regular pentagon has equal sides, but different angles. (True/False)

3 The number 36 is square number as well as a cube number. (True/False)

4 If 1 + 2 + … + 10 = 3025, then 4 + 32 + 108 + … + 4000 is equal to
3
3
3
a. 12000 (b) 12100 (c) 12200 (d) 12400
5 The first odd number is 1, the second odd number is 3, the third odd number is 5 and so
on. The 200th odd number is : (a)399 (b) 421 (c) 357 (d) 599

6 Find the missing number in the sequence. 3, 18, 12, 72, 66, 396, _____.

7 The branch of Mathematics which studies the patterns in whole numbers is called___.

8 In mathematics, a number sequence is an ordered list of numbers that follow a specific
pattern or rule. One common example is the arithmetic sequence, where the difference
between each number is the same. For instance, in the sequence 2, 5, 8, 11 …, the
difference between each number is 3. Another important type of sequence is the
geometric sequence, where each term is found by multiplying the previous one by a fixed
number called the common ratio. For example, in the sequence 3, 6, 12, 24, …, each
number is multiplied by 2. The Fibonacci sequence is another famous number sequence
where each number is the sum of the two before it, starting from 0 and 1. These
sequences are found in real life, like in nature, finance and computer science.

(i)Which of the following sequences is an arithmetic sequence?
(a) 2, 4, 8, 16, 32, …(b) 1, 3, 6, 10, 15, …(c) 5, 10, 15, 20, 25, …
(d) 1, 1, 2, 3, 5, …
