What is the 87th term of the arithmetic sequence with this explicit formula
emmasim [6.3K]

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.
