Answer:
2. 1080
3. 56
4. $1665
Step-by-step explanation:
2. 1080 (/6), 180 (/6), 30 (/6), 5
3. 4(6 + 8) = 4 x 14 = 56
4. $75 + 30(53) = $75 + 1590 = $1665
Sum of consecutive integers = n*(n+1) / 2
2,323 = (n^2 +n)/2
4,646 = n^2 + n
n^2 + n -4,646 =0
n = 67.663 which is NOT an integer

Answer:
21, 20, 19, 18, 17
-2, -3, -4, -5, -6
Step-by-step explanation:
term-to-term rule: -1 (subtract 1)
- starting with 21 the sequence of five numbers is: 21, 20, 19, 18, 17
- starting with -2 the sequence of five numbers is: -2, -3, -4, -5, -6
In the first sequence all the terms are positive and in the second one they are negative
