it goes by 5

for the same set of numbers, it ask what is the 25th term, whats an easier way to find it without having to write it all out till i get the 25th one?

there's a formula for arithmetic sequences an = a1 + (n-1)d where a1 is the first term (-7), d is the common difference (5) and n is the term we want (25)
