Find the Common Difference of an Arithmetic Sequence with a1= -5, a4= 10, a11= 45

Math Problem Statement

Find the common difference of the arithmetic sequence with a1= -5, a4= 10 and a11= 45

To find the common difference of an arithmetic sequence, we can use the formula for the $n$ th term of an arithmetic sequence:

$a_n = a_1 + (n-1) \cdot d$

where:
