How to find : First we use the following equation
= +
then we substitute for the first term in the equation which is -27. We also substitute n with 50 and d with the pattern difference.
$latex t_{50} = -27+ (50-1) (3
then we solve for
= -27 +
= -27 + 147
= 120
The general equation for is : –
Now we solve for by plugging in the numbers again
= (2 + (n-1)(d)
= ( 2(-27) + (50-1)(3)
= 25( -54 + 147)
= 25(93)
= 2325
