Answer:
= - 95n
Step-by-step explanation:
Note the difference between consecutive terms in the sequence is constant
- 190 - (- 95) = - 190 + 95 = - 95
- 285 - (- 190) = - 285 + 190 = - 95
- 380 - (- 285) = - 380 + 285 = - 95
This indicates that the terms are an arithmetic sequence with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 95 and d = - 95, thus
= - 95 - 95(n - 1) = - 95 - 95n + 95 = - 95n
Answer:
H
Step-by-step explanation:
Let a represent Ann's height, and let j represent Jay's height
Break up the sentence into the key parts.
"The difference between Ann's and Jay's heights" "is" "half of Jay's height"
"The difference between Ann's and Jay's heights" becomes the expression:
a - j
"is" is math means an equal sign '='
"half of Jay's height" becomes the expression: (1/2)j
Put the 3 parts together and get the equation:
a - j = (1/2)j,
Since all the equations in the answer choices are in terms of a, solve the above equation for a...
a = (1/2)j + j, which is answer H
Answer:
Step-by-step explanation:
Yes it is
The even integer between them is their average value, -88/2 = -44.
Your two integers are -45 and -43.
