Question

Vishal added five consecutive odd numbers. If the sum of the middle three numbers is 45 then which is the greatest number chosen be Karan?​

Answer 1

Answer:

19

Step-by-step explanation:

The general formula of odd no. Is 2n+1

So consider 1st no. Be 2n+1

2nd no. Be 2n+3

3rd no. Be 2n+5 and so on.

As it is given that the sum of 3 middle nos are 45.

So we can write that as: 2n+3 + 2n+5 + 2n+7=45

Thro this equation we can obtain the value of n so does the greatest no. In the given series.

Ans: n =5 and greatest no. Would be 19.
