Question

in an arthmetric sequence, t20=93 and s25 = 1625. Find the term 'a' and the common difference 'd'. (hint: systems of equations might be helpful here)

Answer 1

Lets model the following equation for the difference.

\(\normalsize\color{blue}{ 1625-93=5d }\)

Answer 2

I think that you have a little typo, because such problems usually have whole numbers for the difference.

Answer 3

nope, it's the actual question. is there such thing as an answer that is not possible?
