Answer this plea 17. write a function rule for the following arithmetic sequence and use it to find the 250th term. show your work. −3, 1, 5, 9, …. function rule: determining 250th term:

First check the difference between terms:

So every term differs by 4. The first term in the sequence is . Recursively, the sequence is given by

Then

and so on, with the general rule

Then the 250th term of the sequence would be

what golf ball

step-by-step explanation:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
