Answer:
S12 for geometric series: (-7.5) + 15 + (-30) + ... would be: 10237.5
Step-by-step explanation:
Given the sequence to find the sum up-to 12 terms

As we know that
A geometric sequence has a constant ratio 'r' and is defined by


















∵ 



Thus, S12 for geometric series: (-7.5) + 15 + (-30) + ... would be: 10237.5
