How would you write the sigma notation ∑4n=1(10)(−1/4)n−1 in the expanded series form?(1 point) Responses 10−52+58−532+5128 10 minus Start Fraction 5 over 2 End Fraction plus Start Fraction 5 over 8 End Fraction minus Start Fraction 5 over 32 End Fraction plus Start Fraction 5 over 128 End Fraction 10+52+58+532 10 plus Start Fraction 5 over 2 End Fraction plus Start Fraction 5 over 8 End Fraction plus Start Fraction 5 over 32 End Fraction 10−52+58+532 10 minus Start Fraction 5 over 2 End Fraction plus Start Fraction 5 over 8 End Fraction plus Start Fraction 5 over 32 End Fraction 10−52+58−532 10 minus Start Fraction 5 over 2 End Fraction plus Start Fraction 5 over 8 End Fraction minus Start Fraction 5 over 32 End Fraction
The sigma notation ∑4n=1(10)(−1/4)n−1 can be expanded as:
10 - 5/2 + 5/8 - 5/32
