How do you write the equation for this sequence 10, 20, 30, 40 Unknown008 Posts: 8,076, Reputation: 723 Uber Member #2 Nov 9, 2011, 10:23 PM
Try using the arithmetic progression equation?

Tn is the nth term,
a is the first term,
n is the term number in the sequence (n = 1 means first, n = 2 means second, etc)
d is the common difference (the difference between any two consecutive terms).

Tn=10n
