What don't you understand?
im not sure what numbers i should fill in the blanks with
A(n) = __x___ + __x__ (n– 1 )
250, 140? idk
should n be 10?
(10-1)
A(n) = __x___ + __x__ (n– 1 )
250, 140? idk
should n be 10?
(10-1)
when n = 0 (now) weight is 250
when n = 1, weight is 240 -----> 250 - 1(10)
when n = 2 weight = 230 -------> 250 - 2(10)
....
when n = n, weight = 250 - 10n
I don't know about the A(n) = d + a1(n – 1)
usually d is reserved to represent the common difference, which in
this case would be 10, a1 usually is the first term
