Answer:Step-by-step explanation:
If there is a sequence and if we are to find its 87th term we must have the general term formula for the sequence.
Normally for sequences which follow a pattern there will be a formula for nth term.
Example is arithmetic sequence nth term = a+(n-1)d where a is the I term and d the common difference.
Similarly for geometric sequence nth term
= is the nth term
Thus to find the 87th term, we must be able to find out the pattern of the sequence by which any term is related to its previous term
Either general term formula or recurring formula should be given to get the 87th term
Step-by-step explanation: is arithmetic sequence nth term = a+(n-1)d where a is the I term and d the common difference. Still stuck? Get 1-on-1 help from an expert tutor now.

999/7 is just over 142
100/7 is just over 14
so there are (142 - 14) = 128 numbers that are multiples of 7, hence there are 999-99-128 = 772 numbers that are not multiples of 7.

Step-by-step explanation:
Answer:
Length = 5
Width = 21
Step-by-step explanation:
(x)(x + 16) = 105
x^2 + 16x = 105
x^2 + 16x - 105 = 0
(x - 5) x ( x + 21) = 0
x - 10 = 0
x = 5
x + 21 = 0
x = -21
Now that we have the zeroes.
We have to find the most viable one to put in.
Using -21 would not make sense, so we will use 5.
Plug it in:
x = 5
(5) (5 + 16) = 105
5 ( 21) = 105
