Sn = -8n + 2S0 = -8(0) + 2 = 2S1 = -8(1) + 2 = -6S2 = -8(2) + 2 = -14S3 = -8(3) + 2 = -22S4 = -8(4) + 2 = -30S5 = -8(5) + 2 = -38
Six plus five is eleven.

Yes, it can.
There are 3 terms in the algebraic expression of: 3y+9+7x
2,1,0 is th sequence of its terms
5, 8, 11, 14 and 17.

9, 10, 11 and 12
They are: 7, 10, 13, 16, and 19
5, 7, 9, 11 and 13
11, 14, 19, 26 and 35.
They are 7, 10, 13, 16 and 19.
4, 6, 8, 10, 12
What does N equal? Well to solve the problem you would do N+7x1, N+7x2, N+7x 3, N+7x4, N+7x5 to figure out the first five terms.
12+7=8, 22+7=11, 32+7=16, 42+7=23
Starting from 1, your get: [4n + 5] = 9, 13, 17, 21, 25 Basically you find the first one and add 4 each time.
