QuestionFind the sums of these sequences using Gauss's method (no formulas): a. $1+2+3+\ldots+39$ b. $1+3+5+\ldots+2609$ c. $3+6+9+\ldots+300$ d. $1000+990+\ldots+10$

Studdy Solution
Calculate the sum of sequence d.
$$Sum_d =1010 \\times50 =50500$$a. The sum of the sequence is780b. The sum of the sequence is1703665c. The sum of the sequence is15150d. The sum of the sequence is50500
