Final answer:
To find the value of Sn, substitute the value of n into the formula Sn = (n − 1)² + 1 and perform the calculations to get the final value. Sn will be one more than the square of one less than n.
Step-by-step explanation:
The question is asking to find the value of Sn, given the formula Sn = (n − 1)² + 1. The formula itself is straightforward, where n represents the term number in a sequence or series. To get the value of Sn, you would simply substitute the value of n you have into the formula and perform the arithmetic operations. The final value of Sn will be one more than the square of one less than n. For example, if n is 3, then Sn would equal to (3 − 1)² + 1, which calculates to 4 + 1, thus Sn equals 5.
