Answer:
step 1 Address the formula, input parameters & values.
Input parameters & values:
The number series 1, 3, 5, 7, 9, . . . . , 1999.
The first term a = 1
The common difference d = 2
Total number of terms n = 1000
step 2 apply the input parameter values in the AP formula
Sum = n/2 x (a + Tn)
= 1000/2 x (1 + 1999)
= (1000 x 2000)/ 2
= 2000000/2
1 + 3 + 5 + 7 + 9 + . . . . + 1999 = 1000000
Therefore, 1000000 is the sum of first 1000 odd numbers
