Answer:

14400

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.
