Step-by-step explanation:
step 1 Address the formula, input parameters & values.
Input parameters & values:
The number series 1, 3, 5, 7, 9, . . . . , 239.
The first term a = 1
The common difference d = 2
Total number of terms n = 120
step 2 apply the input parameter values in the AP formula
Sum = n/2 x (a + Tn)
= 120/2 x (1 + 239)
= (120 x 240)/ 2
= 28800/2
1 + 3 + 5 + 7 + 9 + . . . . + 239 = 14400
Therefore, 14400 is the sum of first 120 odd numbers.
