It's urgent, Please answer, Make Sure you Round it The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).

460, 451,442

Find the 37th term.

Clearly these three terms are making an arithmetic sequence, with :

Now, we have to find 37th term of sequence =

Now, we know that :

Now, by substituting values of a and d :

Hence, value of 37th term of given sequence is 136.

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
