Which of the following is correct to continue the sequence of 105, 110, 115, 120?

• 125, 130, 135, 140

• 121, 122, 123, 124

• 115, 110, 105, 100

• 125, 130, 135, 145

Answer explanation

The sequence increases by 5 each time: 105, 110, 115, 120. Continuing this pattern, the next numbers are 125, 130, 135, and 140, making '125, 130, 135, 140' the correct choice.

Which of the following is correct to continue the sequence of 102, 104, 106, 108?

• 110, 112, 114, 116

• 109, 110, 111, 112

• 110, 112, 114, 118

• 106, 104, 102, 100

Answer explanation

The sequence increases by 2 each time: 102, 104, 106, 108. Continuing this pattern, the next numbers are 110, 112, 114, and 116, making '110, 112, 114, 116' the correct choice.

Which of the following is correct to continue the sequence 103, 106, 109, 112?

• 115, 118, 121, 124

• 113, 114, 115, 116

• 115, 118, 121, 126

• 109, 106, 103, 100

Answer explanation

The sequence increases by 3 each time: 103 + 3 = 106, 106 + 3 = 109, 109 + 3 = 112. Continuing this pattern, 112 + 3 = 115. The correct choice is 115, 118, 121, 124, as it follows the same increment.

Which of the following is correct to continue the sequence of 110, 120, 130, 140?

• 150, 160, 170, 180

• 141, 142, 143, 144

• 150, 160, 170, 190

• 140, 130, 120, 110

Answer explanation

The sequence increases by 10 each time: 110, 120, 130, 140. Continuing this pattern, the next numbers would be 150, 160, 170, and 180, making '150, 160, 170, 180' the correct choice.

If I have 7 groups of 3, the total/sum is...

• 21

• 20

• 7

• 10

Answer explanation

To find the total of 7 groups of 3, multiply 7 by 3. This gives 7 x 3 = 21. Therefore, the correct answer is 21.

If I have 7 groups of 2, the total/sum is...

• 14

• 9

• 13

• 5

Answer explanation

To find the total of 7 groups of 2, multiply 7 by 2. This gives you 14. Therefore, the correct answer is 14.

If I have 7 groups of 5, the total/sum is...

• 35

• 12

• 2

• 30

Answer explanation

To find the total of 7 groups of 5, multiply 7 by 5. This gives 7 x 5 = 35. Therefore, the correct answer is 35.

If I have 7 groups of 10, the total/sum is...

• 70

• 35

• 3

• 17

Answer explanation

To find the total of 7 groups of 10, multiply 7 by 10. This gives 7 x 10 = 70. Therefore, the correct answer is 70.

If I divide 18 into 3 groups, each group is...

• 15

• 6

• 5

• 21

Answer explanation

To find the size of each group when dividing 18 into 3 groups, divide 18 by 3. This gives 18 ÷ 3 = 6. Therefore, each group contains 6.

If I divide 18 into 2 groups, each group is...

• 9

• 16

• 6

• 19

Answer explanation

Dividing 18 into 2 equal groups means each group gets half of 18. Half of 18 is 9, so each group is 9. The other options (16, 6, 19) do not represent equal divisions of 18.
