321.7. It's rounded down to the appropriate number of figures.
Answer:
No
Step-by-step explanation:
She needs 3 bananas for each loaf of banana bread.
She needs 3*9=27 bananas for 9 loaves.
She has only 25, she is 2 bananas short
All you have to do is rotate the current dots, and bam.
In the expression that you are given, n is the is number in the sequence. So in this scenario, n=16. So substitute the 16 into the equation.

. So the 16th term in the sequence is -25.
Using Gauss's method
Total number of terms = [15-(-129)]/4+1=36+1=37
Add
S=15+11+7+....-125-129
S=-129-125-...+7+11+15
--------------------------------
2S=-114-114-114...(37 times)
=>
sum=S=(1/2)*(-114)*37=-2109
Using AP, T(n)=15+11+7+....-129
T(n)=19-4n => T(1)=15, T(37)=-129
S(n)=(1/2)(37)(T(1)+T(37)=(1/2)37(15-129)=2109
