Answer:
Which number should follow this sequence? *
144 121 100 81 64
Answer by mikeebsc(26) (Show Source): You can put this solution on YOUR website!
144-121=23
121-100=21
100-81 =19
81-64 =17
Each step is lowering the value subtracted by 2, so we take 17 and subtract 2.
17-2=15
We then subtract 15 from 64.
64-15=49
49 is the next number in the sequence
Hope this helps. Good luck!
Given data:
100 - 81 = 19
121 - 100 = 21
144 - 121 = 23
To find:
Three more expressions
Step-by-step explanation:
Here 100 - 81 = 19
121 - 100 = 21
144 - 121 = 23
From this we can say that, we are subtracted a square number from its previous square number.
The next numbers of 144 are 169, 196, 225, 256, 289, etc.
So now we have the following pattern:
169 - 144 = 25
196 - 169 = 27
256 - 196 = 29
289 - 256 = 31
and similarly we can find other expressions.
Final answer:
The complete pattern is
100 - 81 = 19
121 - 100 = 21
144 - 121 = 23
169 - 144 = 25
196 - 169 = 27
256 - 196 = 29
289 - 256 = 31
