Hi guys, me again,
last one for the day...
T1=2, T2=6 and T3=12. Determine the nth term formula.
so I said:
This gives me the formula: Tn = n(n+1)
My problem is, they ask to determine which term will have a value of 420?....I cannot use the formula I got to...so I must have gone wrong somewhere. Could someone please show me my error?...thank you all kindly..
