Test: Worksheet Solutions: Patterns and Symmetry - 1 - Class 1 MCQ

The pattern involves decreasing the first two digits by 89, then 89 again, and alternating letters. The next term after 438CC is 549DD, as it continues the pattern of subtracting by 89 and changing the letters in sequence.

The sequence decreases by 10 in the first term and 10 in the last character's letter. Thus, the next term is 395D, followed by 385E and 375F.

The pattern alternates increasing the number by 1 and 2 and cycling through letters. Therefore, 15D is the next term, followed by 16E and 17F.

This sequence increases by 5 each time. Thus, the next number after 66 is 71, followed by 76 and 81.

This sequence increases by 10 each time. Hence, the next term is 63, followed by 73 and 83.

The first two letters increment by one for each term, while the number decreases by 1. Therefore, the next term is NO6.

This sequence decreases by 2 in the alphabet. Thus, after S comes Q.

This is the Fibonacci sequence where each number is the sum of the two preceding ones. Therefore, 5 + 8 equals 13, which is the next term.

This pattern shows a decrease in the first number by 1 and the corresponding letter increases sequentially. Thus, the next term is 6D4.

The pattern alternates between numbers and letters, increasing by 3 each time. Therefore, the next letter is N.

The equation shows that 5 x 5 x 5 equals 125, which is also the sum of consecutive odd numbers starting from 21. The next odd number is 25.

In this sequence, each letter moves forward in the alphabet by one position for each term. Thus, the next term is OIJ.

This sequence increases by 1000 and then by 100. Therefore, the next term is 10134.

The sequence shows letters incrementing by one and the numbers decreasing by one. Thus, the next term is DD6E.

The sequence alternates between letters incrementing and decrementing in the alphabet while increasing by 2 in numbers. Therefore, the next term is C49.

The pattern indicates that 5 cubed equals the sum of consecutive odd numbers starting from 21. The next odd number is 25.

This sequence consists of perfect squares. The next term, 25, is the square of 5.

This sequence doubles each number. Therefore, doubling 16 gives 32 as the next term.
