Answer:3775

Step-by-step explanation:x | 1 2 3 4

y | 2 – – 11

x | 1 2 3 4

y | 2

5811y = 3x – 1

At the 50th term, you get the number 149. I currently cannot think of a simpler and easier way than to manually add up all the numbers that follow the given equation between 2 and 149 (your 1st and 50th terms). When you add up all those numbers, you get your final answer (as you’ve given me) of 3775.

Hope this helps!
