Answer:
a₁ = 37
Step-by-step explanation:
In an arithmetic progression the common difference d is
d = a₂ - a₁ = a₃ - a₂ , that is
2x - 18 - (x + 1) = 2x - 1 - (2x - 18) ← distribute and simplify both sides
2x - 18 - x - 1 = 2x - 1 - 2x + 18
x - 19 = 17 ( add 19 to both sides )
x = 36
Thus
a₁ = x + 1 = 36 + 1 = 37
Answer:
a: 17m + m
Step-by-step explanation:
Each one can answer 17 questions in 1 minute.
Each one can answer 17m questions in m minutes.
The total they can answer is 17m + 17m = 34m.
Every expression that is equal to 34m represents the amount they can both answer in the same number of minutes.
The expression we are looking for does not equal 34m.
a: 17m + m = 18m
b: 34m = 34m
c: 2(17m) = 34m
d: 17m + 17m = 34m
Only choice a does not equal 34m.
Answer: a: 17m + m
