Gce Model Questions Vol1 2021 Christian Religious Studies Question 26

During Paul's first missionary journey he founded a certain number of churches in the first year, and each subsequent year of that journey he founded twice as many as the previous year. The first journey lasted \(2\) years. In the second journey (lasting \(3\) years) the number of churches founded each year was three more than the number founded in the corresponding year of the first journey (if the first journey had no corresponding year, treat its number as 0). In the third journey (lasting \(4\) years) the number of churches founded each year equalled the sum of the churches founded in the same year of the first and second journeys (again treating missing years as 0). If the total number of churches Paul founded across all three journeys was \(210\), how many churches did he found in the first year of his first journey?
