1. note constant d = 2
arithmetic sequence
straight line of slope 2
posted by Damon

2. constant d again
y = m x + b
y = 2.3 x + 3posted by Damon

3, whoa, climbing faster
try
y(n+1) = 3 y(n)
geometric
ratio is always 3
or r = 3
y = 1.4 * 3^(x)
try x = 4
y = 1.4 * 3^4 = 1.4 * 81 = 113.4
it workedposted by Damon
