Final answer:

The expansion of the series sum from n equals 1 to 4 of 2 to the n plus 1 power is calculated by finding the value of 2 to the power of (n+1) for each n and adding them, resulting in 4 + 8 + 16 + 32, which sums up to 60.

Step-by-step explanation:

The student has asked about the expansion of the series sum from n equals 1 to 4 of 2 to the n plus 1 power. Expanding this series involves calculating the value of the expression 2(n+1) for each value of n from 1 to 4 and adding the results together.

Let's calculate each term:

  • For n=1: 2(1+1) = 22 = 4
  • For n=2: 2(2+1) = 23 = 8
  • For n=3: 2(3+1) = 24 = 16
  • For n=4: 2(4+1) = 25 = 32

The expansion of the series is the sum of these values:

4 + 8 + 16 + 32 = 60
