Step-by-step explanation:
Consider the following list:
3+5=8=2³
7+9+11=27=3³
13+ 15 +17+19=64=4³ 21+23+25+27 +29=125=5³
31+33 +35+37+39+41=216=6³
Following this pattern, if we want 10³, there are 10 terms in the list. The first term of the series start as
n²-n+1=10²-10+1=100-10+1=91 Thus, the exquation is
91 +93 +95 +97 +99+101 + 103 +105 + 107 + 109 = 10³ So, there are 10 possible consecutive odd numbers sum upto 1000.
