Hello. I have been a 6th grade math teacher for 25 years. I have not been to school myself in 25 years, many workshops, but not school. I please need help with a math problem explained, if possible, on a middle school level. Thank you.
The sum of the first three terms of a geometric sequence of positive integers is equal to seven times the first term, and the sum of the first four terms is forty-five. What is the first term of this sequence?
