Adding a few consecutive numbers is easy and can be done mentally. Let us learn how
to do it.
a. Adding an odd number of Consecutive terms
rule: Sum = Middle term × Number of terms
example 1. 24 + 25 + 26 = ? example 2. 71 + 72 + 73 + 74 + 75 + 76 + 77 = ?
Solution. Number of terms = 3 Solution. Number of terms = 7
Middle term = 25 Middle term = 74
Sum = 25 × 3 = 75 Sum = 74 × 7 = 518
example 3. 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 =?
Solution. Number of terms = 9
Middle term = 16
Sum = 16 × 9 = 144
