Accepted Solution

A:
Sum of Option 2 does not equal to othersStep-by-step explanation:We have to find each sum to check which is a outlier.so,Option 1:βˆ‘i^2 where i = 1 to Β 3[tex]Sum = 1^2+2^2+3^2\\=1+4+9\\=14[/tex]Option 2:βˆ‘i^3 where i = 1 to 2So,[tex]Sum = 1^3+2^3\\= 1 +8\\=9[/tex]Option 3: βˆ‘(i+1) where i = 1 to 4[tex]Sum = (1+1) + (2+1) +(3+1) +(4+1)\\=2+3+4+5\\=14[/tex]Option 4:βˆ‘(2i-2) where i = 4 to 5[tex]Sum = [2(4)-2]+[2(5)-2]\\=(8-2)+(10-2)\\=6+8\\=14[/tex]Hence,Sum of Option 2 does not equal to othersKeywords: Sum, FormulasLearn more about summation at:brainly.com/question/12973601brainly.com/question/13063819#LearnwithBrainly
