Whats the question ;-;
Step-by-step explanation:
\[\sum_{n=1}^{7} 2(-2)^{n-1}\]
Answer:
80
Step-by-step explanation:
0, 3, 8, 15, 24, <u>35,</u> <u>48,</u> <u>63,</u> <u>80</u> which is the nth term
first step you have to find how many steps the sequence was going with.
examples= from 0 to 3 the steps were 3
=from 3 to 8 the steps were 5
= from 8 to 15 the steps were 7
you will recognize that the steps the sequence is going with is odd numbers.
so you will use the odd numbers until you find what you need. which leads you to 80 which is the nth number in the sequence.
I think you would put 570 in the blank since 19 x 3 = 57
