Find the sum of the following arithmetic progressions:
1, 3, 5, 7, … to 12 terms
for the given AP the first term a is 1, and common difference d is a difference of the second term and first term, which is 3 - 1 = 2
To find: the sum of given AP
The formula for sum of AP is given by
Substituting the values in the above formula
s = 6 × 24
s = 144
