Answer:

17 + 3n

Step-by-step explanation:

20, 23,26 ..............

This is an arithmetic series

First term = a = 20

Common difference = second term -  first term

                               d = 23 - 20 = 3

nth terms = a + (n-1)*d

               = 20 + (n -1) *3

               = 20 + n*3 - 1*3

              = 20 + 3n - 3

               = 20 - 3 + 3n

              = 17 + 3n

Plz, answer! 34 + 2 ⋅ 5 =
8_murik_8 [283]

3^{4} + 2 × 5

To evaluate apply the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

Parentheses  

There are none for this steps so go on to the next step

Exponent:

3^{4}

81

so...

81 + 2 × 5

Multiplication:

81 + 2 × 5

2 × 5

10

so...

81 + 10

No division in this equation so skip this step and go to the next one

Addition:

81 + 10

91

Hope this helped!
