Answer:
Step 1
Address the formula, input parameters & values.
Input parameters & values:
The number series 1, 3, 5, 7, 9, . . . . , 19.
The first term a = 1
The common difference d = 2
Total number of terms n = 10
Step 2
Apply the input parameter values in the AP formula
Sum = n/2 x (a + Tn)
= 10/2 x (1 + 19)
= (10 x 20)/ 2
= 200/2
1 + 3 + 5 + 7 + 9 + . . . . + 19 = 100
Therefore, 100 is the sum of first 10 odd numbers.
