Answer:
c) 1,381.5.
Step-by-step explanation:
First term = 3.1 *1 - 2 = 1.1
2nd term = 3.1*2 - 2 = 4.2
3rd term = 3.1*3 - 2 = 7.3
so the common difference d = 3.1.
S30 = (30/2) [ 2* 1.1 + (30-1) * 3.1)]
= 1,381.5.
Its 125,000 because 250 squared is 125,000 cause of math. i really dont wanna go to school and life sucks:)
