Answer: Algebraic: 15-22
Simply:-7
Step-by-step explanation:
Less than means to take away from, so in this case we are taking away 22 from 15
286 is the sum of the series below. You can plug this in or use long addition.
Either that or you make an average and that's your answer.
D
the n th term (explicit ) formula for a geometric sequence is
= 

The given explicit formula therefore has
= 5 and r = - 
The recursive formula, allows us to find the next term in the sequence from the previous term
Here the next term in the sequence is obtained by multiplying the previous term by - 
=
(-
) with
= 5
