I'm in year 10 and I'm stuck on my GCSE math homework.

A geometric sequence begins with 7 and has a common ratio of the cubed root of 3. Find the first 5 terms of the sequence.

Could someone please explain how I work it out? thank you x

Each term in a geometric sequence of first term a and common ratio r increases by a factor of r each time, so it goes a, ar,ar^2, ar^3,... Just substitute your values of a and r.
