Answer:
The number series 1, 3, 5, 7, 9, . . . . , 199.
The first term a = 1
The common difference d = 2
Total number of terms n = 100
step 2 apply the input parameter values in the AP formula
Sum = n/2 x (a + Tn)
= 100/2 x (1 + 199)
= (100 x 200)/ 2
= 20000/2
1 + 3 + 5 + 7 + 9 + . . . . + 199 = 10000
Therefore, 10000 is the sum of first 100 odd numbers.
