A) Show/hide Answer
If we find the pattern of a series, we can write the next terms of the series.
The general number patterns are the difference between the numbers in the sequence and we use that fact to find out the next numbers.
Look at the series and try to write the next terms:
1) 3 8 13 18 23 28 ----- ----- -----
We see that each term is 5 more than the previous term,
So, we write the next term as 28 + 5 = 33, 33 + 5 = 38, and 38 + 5 = 43.
2) 6 16 26 36 46 ----- ----- ----- -----
The term increases by 10
46 + 10 = 56, 56 +10 = 66, 66 +10 = 76, 76 + 10 = 86
3) 182 172 162 152 ----- ----- -----
The term decreases by 10
152 - 10 = 142, 142 - 10 = 132, 132 - 10 = 122.
Look at these towers:
ADD
6 + 7 = 13, 7 + 4 = 11
13 + 11 = 24.
We can see that when we add the 2 numbers near each other, we get the number above the two numbers.
MULTIPLY
1 × 2 =2, 2 × 6 = 12, and then 2 × 12 = 24.
We can see that when we multiply the numbers near each other, we get the number above those numbers.
Sometimes some information is secret.
So, instead of writing it in normal language, it is coded by writing numbers instead of letters or different letters instead of original letters.
Let us see how each letter can be allotted a number.
So,in number code,
Other codes substitute letters with other letters.
Instead of writing A write Z.
Similarly, instead of B write Y i.e., instead of the first letter write the 26th letter,
Instead of the 2nd letter write the 25th letter.
So, instead of C i.e., 3rd letter, write X i.e., 24th letter.
So, in this code
Many secret codes can be made easily.
To read messages in code, we must know the key to the code i.e., what each letter or number stand for.
Look at these patterns:
♦1
In the above pattern, the sum of any two consecutive numbers is the
2nd number × 2 - 1
Example: in 7 + 8 = 15, 15 = 2 × 8 - 1 = 16 - 1.
♦2
In the above example, the sum is thrice the middle number.
♦1
In the tens place we have, 1 and 1 then 2 and 2, then 3 and 3, 4 and 4 and so on.
♦2
The digits in the tens place go on increasing till 9.
The next numbers again increase from 9 to 10 and 10 to 11 and so on.
Look at these beautiful tiling patterns:
We notice a difference between the tile patterns of a, b, c and d, e, f.
The tiles in pattern a, b, c fit each other without gaps but d, e, f tile patterns have gaps in between.
Shapes that fit together without gaps in between are said to be 'tesselate'.
The tilings in a, b, and c are called 'tesselations'.
