Question

Write an expression to describe a rule for the sequence. Then find the 100th term in the sequence.

Answer 1

Answer:

7n-4;696

Step-by-step explanation:

I look at it as having ordered pairs (1,3), (2,10), (3,17), etc

looks like the y's increase by 7 for every increase of 1 in the x's, so the slope = 7

thus y = 7x + b

plug in (1,3) ----> 3 = 7 + b or b = -4

y = 7x - 4

in sequence terms: termn = 7n - 4

term100 = 7(100)-4 = 696
