Answer:
121
Step-by-step explanation:
This is an arithmetic sequence.
First term a = -15
Common difference [d] = second term - first term
= -11 - [-15] = -11 + 15 = 4
nth term = a + (n-1) * d
35th term = -15 + (35 - 1) * 4
= -15 + 34 * 4
= - 15 + 136
= 121
Pounds of butter=1/10 (potatoes)
=1/10 (12.5)
=1.25 pounds
Ellie uses 1.25 pounds of butter
It is probably 0,2,4,6 because other ones go "out of the sequence".
Hope this helps. :)
