Series are sum of a given sequence.. The sum of the given expression is -33
<h3>Sequence and series</h3>
Series are sum of a given sequence. According to the given expression
∑∑k=1 (k^2-5k-3)
Taking the sum from k = 1 to k = 4
Sum = (1-5-3) + (4-10-3) +(9-15-3)+(15-20-3)
Sum = (-7) + (-9) + (-9) + (-8)
Sum = -33
Hence the sum of the given expression is -33
