Answer:
m = -4.46
Step-by-step explanation:
-21.536 = -1.6(9 - m)
1.) Distribute.
-21.536 = -14.4 + 1.6m
2.) Add 14.4 to both sides.
-7.136 = 1.6m
3.) Divide both sides by 1.6.
-4.46 = m, or m = -4.46.

Sequence: 1, 3, 6, 10, 15, …
If sequence is arithmetic,
If sequence is geometric,
<u>Check </u>for arithmetic:
Hence, the sequence is not arithmetic
<u>Check </u>for geometric:
Hence, the sequence is not geometric
Solution:
a1 = 1
an = an-1 * -5
100=10+25+65
is it like that?I'm not sure about this
