What is the 100th term of the arithmetic sequence below?<br> 4, 11, 18, 25
galina1969 [7]

Answer:

a₁₀₀ = 697

The nth term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 4 and d = a₂ - a₁ = 11 - 4 = 7 , then

a₁₀₀ = 4 + (99 × 7) = 4 + 693 = 697

y=-\frac{4}{3}x+b

plug in x and y

16=-4/3(3)+b

b=20
