Dear student,

This question can be solved by an Arithmetic Progression
where,
depth at which final sample collected, an=35intervals to collect a sample, d=5and Starting collected at 5m below the surface⇒ a=5Number of samples he collected, n=?Now, we know an=a+(n-1)d⇒35=5+(n-1)×5⇒35=5+5n-5⇒35=5n⇒n=355⇒n=7Thus, the number of samples he collected is 7
