To find the sum of the first 8 terms of the given sequence, we need to identify the common ratio (r) and the first term (a1).Given sequence: 100, 123, 151.29,...Step 1: Find the common ratio (r).To find the common ratio, we can divide any term by its previous term.r = 123 / 100 = 1.23Step 2: Find the first term (a1).The first term (a1) is the first number in the sequence.a1 = 100Step 3: Use the formula for the sum of a finite geometric series.The formula for the sum of a finite geometric series is:
Step 4: Substitute the values into the formula.
Step 5: Calculate the sum.
Therefore, the sum of the first 8 terms of the given sequence is approximately 1000.00.
