An arithmetic progression has 241 terms and a
common difference of 0.1 given the sum of the
terms is 964. Find the first term.



Substitute n=241 and d=0.1



And substitute S241 = 964







Clear the fraction by multiplying both sides by 2



Divide both sides by 241



Subtract 24 from both sides



Divide both sides by 2



First term is -8
