Answer:
b=16
Step-by-step explanation:
75%=75/100=3/4
3/4*b=12
b=12/1*4/3
b=16
To find:
- 66th term of the arithmetic sequence -28, -45, -62, ...
Solution:
- First term (a) = -28
- Comman difference (d) = -45 - (-28) = - 17
- n = 66
Using formula:
Substituting values in the formula:
Hence,
- <u>66th term</u> of the arithmetic sequence is -<u>1133</u>.
Pretty sure that’s a -13.178294573643404
% difference. I really hope this is right and I really hope it helps!
