Identifying Missing Numbers in Patterns

The video tutorial explores finding missing numbers in sequences by incrementing or decrementing by one or two. It demonstrates how to identify missing numbers by adding or subtracting consistently in each step, providing examples for each method.

What is the next number in the sequence starting from 8, if each number increases by 1?

• 9

• 10

• 12

• 11

If a sequence starts at 10 and each subsequent number increases by 2, what would be the third number in the sequence?

• 14

• 12

• 18

• 16

In a decreasing sequence starting from 14, what is the number after subtracting 2 twice?

• 10

• 12

• 8

• 6

What number do you get when you subtract 1 from 19 in a descending sequence?

• 15

• 18

• 17

• 16

Identify the missing number in the sequence: 20, 19, ?, 17.

• 15

• 14

• 16

• 18
