BEFORE, AFTER AND BETWEEN

 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

Q – 10. (a) The day that comes Saturday and Monday is Sunday, as it comes after Saturday, but before Monday
