Q. Evaluate the summation below.2i=0∑3(3i−3i2)Answer:
Write Series Expression: Write down the series to be evaluated.We need to evaluate the summation of the series given by the expression 2×∑i=03(3i−3i2). This means we will calculate the sum for each value of i from 0 to 3, multiply each term by 2, and then add up all the terms.
Calculate Series Terms: Calculate the terms of the series for each value of i. For i=0: 2×(3×0−3×02)=2×(0−0)=0 For i=1: 2×(3×1−3×12)=2×(3−3)=0 For i=2: 2×(3×2−3×22)=2×(6−12)=−12 For i=3: 2×(3×3−3×32)=2×(9−27)=−36
Add Terms: Add up all the terms calculated in Step 2.Sum = 0+0−12−36=−48
Final Answer: State the final answer.The sum of the series is −48.
