Find an explicit formula for the arithmetic sequence 37, 74, 111, 148... Note: the first term should be a (1)

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
