150 (50) + (49 + 48 + 47 + 46 + 45 + 44 + 43 + 42....+1) =
You can either add all these numbers up individually or you can figure out the second half of the equation:
Start by adding the ends up - Starting with 50 will give you 25 pairs of numbers - we'll subtract the extra 50 at the end:
50 + 1 = 51
49 + 2 = 51
48 +3 = 51
..... hint- they all equal 51
51 * 25 = 1275
Subtract the extra 50 = 1275-50 = 1225
150 (50) + 1225 = 8725
