Question

write an explicit formula for the arithmetic sequence

62, 59. 56, 53

Answer 1

nth term =a+(n-1)*d where a is the first term here its 62
and d is the common difference here u can calculate d by subtracting the next number in sequence with its preceding number
here d is 59-62 = -3 , also 56 - 59 = -3 its common , thats y we call it common difference :)

now nth term = 62+(n-1)*(-3)
= 62 -3n+3
= 65-3n
