Ok so easy. So the equation is y=mx+b where m is the slope. You get slope by doing y2-y1 /x2-X1. Ok so I'm assuming you know which one is y1 and which one is y2 if not comment back and I answer.
Answer:
5115
Step-by-step explanation:
We know:
a_1 = 5 the first term in the geometric sequence.
r = 2
We want Sum a_i for i = 1 to 10
a_n = 5* 2^(n-1)
Sum a_i for i = 1 to 10 = G
G = a_1* (2*2^(n-1) - 1) / (2 - 1)
G = 5 * (2^(n) - 1)/ (2 - 1), n = 10
G = 5* (2^(10) - 1)
G = 5*(1024 - 1) = 5*(1023) = 5115
