Complete the previous and following number:
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The problem provides us with the number .
Step 2: To find the predecessor, we calculate .
Step 3: To find the successor, we calculate .
Therefore, the numbers that complete the sequence are and .
What number follows 70,099?
When adding 1 to 10999, the 9 in the ones place becomes 10, so we write 0 and carry 1 to the tens place. This continues: tens (9+1=10), hundreds (9+1=10), thousands (0+1=1). The result is 11000!
When you add 1 to any number ending in 999, all the 9s become 0s and the digit to the left increases by 1. For example: 2999 + 1 = 3000, 10999 + 1 = 11000.
Predecessor means "comes before" (subtract 1), and successor means "comes after" (add 1). Think: predecessor = previous, successor = succeeding/following.
Yes! In number sequences, consecutive numbers are exactly 1 apart. The predecessor is always exactly 1 less and the successor is always exactly 1 more than the given number.
Practice with smaller numbers first! Try 99 + 1 = 100, then 999 + 1 = 1000. Always check your answer by working backwards: does 11000 - 1 = 10999? ✓
