Answer 1

Answer:

Address the formula, input parameters & values.

Input parameters & values:

The number series 1, 3, 5, 7, 9, . . . . , 59.

The first term a = 1

The common difference d = 2

Total number of terms n = 30

step 2 apply the input parameter values in the AP formula

Sum = n/2 x (a + Tn)

= 30/2 x (1 + 59)

= (30 x 60)/ 2

= 1800/2

1 + 3 + 5 + 7 + 9 + . . . . + 59 = 900

Therefore, 900 is the sum of first 30 odd numbers.
