Hi guys, me again,

last one for the day...

T1=2, T2=6 and T3=12. Determine the nth term formula.

so I said:

T1=2

T2=6

T3=12

But:

2=1.2

6=2.3

12=3.4

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..
