Question

what is sum of all odd numbers from 1 to 5000​

Answer 1

Answer:

$\huge\mathbb\purple{step \: 1}$

Address the formula, input parameters & values.

Input parameters & values:

The number series 1, 3, 5, 7, 9, . . . . , 9999.

The first term a = 1

The common difference d = 2

Total number of terms n = 5000

$\huge\mathbb\purple{step \: 2}$

apply the input parameter values in the AP formula

Sum = n/2 x (a + Tₙ)

= 5000/2 x (1 + 9999)

= (5000 x 10000)/ 2

= 50000000/2

1 + 3 + 5 + 7 + 9 + . . . . + 9999 = 25000000

Therefore, 25000000 is the sum of first 5000 odd Number.

hope it helps you buddy ✌️✌️✌️
