Find the formula for 2, 10, 18, 26, ...

To find the terms in a linear sequence;

Tn = a + (n-1) d

a = 2 (first term)

n = (nth term)

d = (difference between two terms, e. g T3 - T2)

From the given data;

Tn = 2 + (n-1) 8

Open the bracket

Tn = 2 + 8n - 8

Tn = 8n - 6

Therefore, the formula for the sequence is: Tn = 8n - 6
