Question

How many consecutive natural number starting from 1 should be added to get 300

Answer 1

consecutive natural numbers will form AP

1,2,3,4,5,6............n

Here, a = 1 d = 1

Sn=300

We are given the sum of an AP which is

Sn=n/2(2a+(n-1)d)

300 = n/2(2+n-1)

600 = n + n²

n² + n - 600 = 0

After solving the above quadratic equation we get

n = 24
