# 25-3n work out the first 3 sequences?

This is actually really simple for the first term you substitute 1 into n: 25 - 3(1) 25 - 3 = 22 for the second term you substitute 2 into n: 25 - 3(2) 25 - 6 = 19 for the third term you substitute 3 into n: 25 - 3(3) 25 - 9 = 16 so the first three terms in the sequence are 22, 19, 16 I hope this helped :)
