Question

write the first five terms of the sequence. find the common difference of tge sequence. write the nth term of the sequence as a function of n.
a1=200
a = a -10
k+1 k

Answer 1

how far have you gotten?

Answer 2

and, it simpler to define this as ak = a{k-1} - 10, that wayt he kth term doesnt need to be mentally altered

Answer 3

if i've understood it correctly
2nd term = a2 = a(2-1) - 10 = 200-10 = 190
CD = -10
first 5 terms are 200,190,180,170,160

Answer 4

nth term = 200 - 10n

Answer 5

thats the issue with starting a seq at n=1, it messes with the count

Answer 6

a1 = 200; yet, 200-10(1) = 190
