Find the nth term for the sequence 45, 40, 35, 30

(n-5)+45
where n is the number, you always take away 5 and you add 45 because that is the first number of the sequence

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
