Question

Write an equation for the sequence 7, 13, 19, 25 using

Answer 1

Answer:   $\bold{a_n=1+6n}$

Step-by-step explanation:

The equation can be found using the formula:

$a_n=a_1+d(n-1)\quad \text{where}\ a_1\ \text{is the first term and d is the difference}$

In the given sequence {7, 13, 19, 25}; a₁ = 7 and d = 13-7 = 6

$a_n=7+6(n-1)\\\\.\quad =7+6n-6\\\\.\quad =1+6n$
