Answer:
44
Step-by-step explanation:
x + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) = 294
Combine all like terms for x and integers
6x + 30 = 294
Minus 30 on both sides
6x = 264
Divide by 6
x = 44
Answer:
x = 2
y = -5
Step-by-step explanation:
2x - y = 9
y = x - 7
2x - y = 9
2x - (x - 7) = 9
2x - x + 7 = 9
x + 7 = 9
x = 2
y = x - 7
y = 2 - 7
y = -5

Step-by-step explanation:
The given formula is a recursive formula which allows a term in the sequence to be found using the previous term.
Given
=
+ 3 with A₁ = 2, then
A₂ = A₁ + 3 = 2 + 3 = 5
A₃ = A₂ + 3 = 5 + 3 = 8
A₄ = A₃ + 3 = 8 + 3 = 11
A₅ = A₄ + 3 = 11 + 3 = 14
The first 5 terms in the sequence are 2, 5, 8, 11, 14
