__PREDECESSOR / SUCCESSOR AND BETWEEN__

**PREDECESSOR**

**Predecessor is that which comes before immediately, or the event that has happened just before the current event. Kim prepares the tea before drinking it, or Jack walks out of his house before going to the market.**

**In
mathematics terms, it is the number that comes, just before a particular
number, or in other words the predecessor is the number – 1. For instance the
number 12 comes before 13, or 13 – 1 = 12. **

** Friday comes before Saturday. June comes
before July. May also comes before July, but it is not the predecessor of July,
since it does not comes immediately before July. June is the month that comes immediately before July. In
everything it is the same case. In numbers also the predecessor of number 21 is
number 20 not the number 19**

**So predecessor is
also known as before, previous, prior or former **

**SUCCESSOR**

**Successor
is that which comes after immediately, or follows it. 16 comes after 15. July
comes after June.**** In real life , if we consider Terence goes to the office
after getting ready, or Olive reads the book after opening it . **

**So mathematically successor
is the number + 1. Successor of the number 1,025 is 1,026 or 1,025 + 1 = 1,026.
The number 1,027 also comes after the number 1,025, but it is not the successor
of the number 1,025 as it does not immediately comes after 1,025. Yes it is the
odd successor of the number 1,025. The number 1,026 is the successor, but it is even not odd **

**BETWEEN**

**The
number 37 comes in between 36 and 38.**

** 36 37 38**

**The day
Thursday comes in between Wednesday and Friday**

** Wednesday Thursday Friday**

**The
month October comes in between September and November**

** September October November **

__ANSWERS WITH EXPLANATIONS __

**Q - 1 .(c) The number that comes
after 78,984 is 78,985, as**

**78,984 + 1 = 78,985**

**Q – 2. (b) The predecessor of the
number 9,876 is 9,875, but 9,875 is odd not even. So it would be 9,874 which is
an even number****
**

**Q – 3. (a) April is the month that
comes after March but before May. Hence April comes in between March and May**

** March April May**

**Q – 4. (d) The odd successor of the
number 5,871 is 5,873. The successor of the number 5871 is 5871 + 1 = 5872, but
the number 5,872 is even not odd. **

**Q – 5. (a) Odd predecessor of the
number 6,789 is 6,787. Even successor of the number 5,678 is 5,680. Difference
between them is 6,787 – 5,680 = 1,107**

**Q – 6. (a) Highest four digit number
is 9,999. Its successor is 9,999 + 1 = 10,000 which is lowest five digit number
also **

**Q – 7. (a) Prime successor of the
number 2,129 is 2,131.**

**Q – 8. (d) Lowest six digit number is
1,00,000. Its predecessor is 1,00,000 – 1 = 99,999. It is highest five digit
number also. Hence answer is both (a) and (c)**

**Q – 9. (c) Even successor of the number 438 is 440. The
odd predecessor of the number 1,670 is 1,669. Their sum is 440 + 1,669 = 2,109**
