What is the 52nd term of the sequence (-38,-45,-52,-

- 395

Step-by-step explanation: The sequence is in form of Arithmetic sequence , if you check properly, the difference between the 2nd number and the 1st number is the same as the difference between the 3 rd and the 2nd ...

This difference is called common difference and it's denote with d.

From the sequence given d = - 7

the 52nd term = a + 51d , where " a" is the first term

                        = - 38 + 51 ( -7 )

                        = - 38 - 357

                        = - 395

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
