Find the sum of a 9-term geometric sequence when the first term is 4 and the last term is 1,024?

It basically means find the sum of 4+8+16+32+64+128+256+512+1024
It would give 2044

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
