Test: Patterns -1 - Class 5 MCQ

The sequence is decreasing by 2 each time.

• Start with 10.
• Subtract 2 to get 8.
• Subtract 2 again to get 6.
• Continue the pattern to get 4.
• The next number is 2 after subtracting 2 from 4.

• Alphabets along with the number on which they come. 
• A1; B2; C3; D4; E5; F6....
• Therefore the next term is E5

The sequence given is 90, 80, 70, 60. To find the next number, observe the pattern:

• The numbers are decreasing by 10 each time.
• Following this pattern, subtract 10 from the last number, 60.
• This calculation results in 50.

Therefore, the next number in the sequence is 50.

• Increasing the series.
• The next answer will be A. 

To find the missing number, observe the pattern:

• The sequence is increasing by adding a specific number each time.
• 4 + 4 = 8
• 8 + 4 = 12
• Continue this pattern by adding 4 to the previous number.

Therefore, 12 + 4 = 16.

The pattern in the sequence involves adding 8 to the previous number:

• Start with 8.
• Add 8 to get 16.
• Add 8 again to get 24.
• Adding 8 once more gives 32.

Therefore, the next number in the sequence is 32.

• List Of Triangular Numbers.
• 0, 1, 3, 6, 10, 15, 21 and so on.
• Therefore 6 is the correct answer.

• 1+3+5 = 9
• 9 = 3²
• Therefore, it is a square number

• Your sequence is 1, 3, 6, 10, ... and the differences are 2, 3, 4, ...
• so actually each term is the sum of all the counting numbers up to the term number.
• So the fifth term in the sequence would be the sum of all the numbers up to 5:
• 1+2+3+4+5 = 15.

• List Of Triangular Numbers. 0, 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, 91, 105, 120,136, 153, 171, 190, 210, 231, 253, 276, 300, 325, 351, 378, 406, 435, 465, 496, 528, 561, 595, 630, 666, 703, 741, 780, 820, 861, 903, 946, 990, 1035, 1081, 1128, 1176, 1225, 1275, 1326, 1378, 1431, and so on.
• Thus, 5 is not a triangular number
