Hello i wondering if anyone could give me a hand solving this
1. the sum of the geometric progression := S
2. the number of terms := n
3. the first term := t
Can you get an equation for the common ratio???
finite G.P S = t * ( 1 - r^n)/(1 - r)
the number i workin off are
S = 292.618
n = 15
t = 50
i dont know the sequence as i'm using this for a c++ program and numbers vary!
