How many total terms are there in the following sequence. 7,10,13,...,391,394
nlexa [21]

Answer: n = 130

Step-by-step explanation:

The sequence is an Arithmetic progression ( AP )

The last term of the sequence is (L) is 394 with the formula

L  = a + ( n- 1 )d . From the sequence, a = 7, d ( common difference ) = 3 and L ( last term ) = 394, and n = ?

Put those values in the formula above and solve for n.

  a + ( n - 1 )d =  L

  7 + ( n - 1 ) x 3  = 394

         7 + 3n - 3   = 394

             4 + 3n     = 394

                    3n     = 394 - 4

                     3n     = 390

                        n     = 130

Use the point slope equation to identify the slope and the coordinates of a point on the line y=1/2(x-1)
gtnhenbr [62]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y = \frac{1}{2}(x - 1) is in this form

with slope m = \frac{1}{2}

note left side of equation can be written as

y - 0 = \frac{1}{2}(x - 1)

the point on the line (a, b) = (1, 0)
