Answer:

n =30 so and is 30

Step-by-step explanation:

try using progression.

Sn=465

a =1

d=1 because because no more information .

put concept of arithmetic progression .

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

solve it for n and u get 30 and -31 so 30 is ur answer

Step-by-step explanation

465 = n(n + 1)/2

930 = n^{2} + n\\

n^{2} + n - 930 = 0

n^{2} + 31n - 30n - 930 = 0

n( n + 31) - 30(n + 31) = 0

(n +31)(n-30) = 0

Therefore n = 30 or (-31)

But number of terms cannot be negative so (-31) is not possible

So n = 30

So 30 consecutive natural numbers should be added to get 45.

I HOPE IT HELPS
