The answer 375. the first 7 is 175 then add 200 to the 175 and that is how you get the full 8 more
area is height times width so multiply 10.5 and 16 that gives you 168
If you work out the constants it says:
25+x²=100
Which simplifies to x=√75 or x=-√75
Common ratio (r) can be found by dividing the second term by the first term.
0.02 / -0.1 = -0.2
an = a1 * r ^ (n - 1)
a1 = first term = -0.1
r = common ratio = -0.2
an = -0.1(-0.2)^(n - 1)...answer is C
Two divided by twenty-two is .090909 repeating
