Class 8 -Exercise 6.1 - Q 8 | Express 49 as the sum of 7 odd numbers

[Redskull]

We can find sum without adding by using formula-

n/2{2a+(n-1)d}

Where
n= number of number in the question for example 1+3+5+7 here n=4 because there are 4 numbers in the question


a= the starting number for example a=1 if the question is 1+3+5+7


d= the difrence between the numbers for example in 1+3+5+7 the difference between the numbers are 2 so d=2

Let me know if it helps😊
