Question

17th question
it is of square root chapter​

Answer 1

Answer:

Without adding, find the sum of 1 + 3 + 5 + 7 + 11

Step-by-step explanation:

well, it is simple

Since they are odd numbers, count how many odd numbers are mentioned in the equation

and they must be consecutive

in this case there are 4 consecutive odd numbers [which is why i underlined them] and the next one [11] is not consecutive

so all you have to do is

find the square of 4

which is 16

and then add the other number

you can double check by adding afterwards

i hope this was helpful

have a good day
