In a g p the sum of the 2nd term and the fifth term is 72 and the sum of the 3rd term and the 6th term is 144 dertermine the the common ratio the first term sum of the first 6 terms

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
