Explanation: Multiply each term by 2 means you take each number and multiply it by 2.
For example:
40 × 2 = 80
This shows that when you multiply 40 by 2, the result is 80.
Q32. Find the next term: 1, 4, 9, 16, 25, ?
Correct Answer:
36
Explanation:
These are squares of consecutive integers:
1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
6² = 36
Q33. What comes next: 121, 144, 169, 196, ?
Correct Answer:
225
Explanation:
These are squares of consecutive numbers, which means each number is multiplied by itself. Here are the squares:These are squares of consecutive numbers:
11² = 121
12² = 144
13² = 169
14² = 196
15² = 225
Q34. Identify the missing term: 7, 14, 28, 56, ?

Q36. Complete the series: 100, 50, 25, 12.5, ?
Correct Answer:
6.25
Explanation: When we say "each term is halved," it means we divide it by 2. For example:
12.5 ÷ 2 = 6.25 This shows that when you take 12.5 and split it into two equal parts, each part is 6.25.
Q37. Find the next term: 3, 9, 27, 81, ?
Correct Answer:
243
Explanation: Each term is multiplied by 3.
81×3=243.
Q38. Find the missing number in the series: 2, 6, 12, 20, 30, ?
Correct Answer:
42
Explanation: The differences between consecutive terms are 4, 6, 8, 10, etc. (even numbers increasing by 2). Add 12 to the last term (30) to get 42.
