Determine if the sequence is arithmetic. If it is find the common difference, the 52nd term 38,47,56,65

497

Step-by-step explanation:

Since if we take the difference between each number i.e.

47 - 38 = 9

56 - 47 = 9

65 - 56 = 9

As the difference is same that means it is a arithmetic sequence

Now

The 52nd term is

a(n) = a +(n-1)d

a(52) = 38 +  (52 - 1) (9)

a(52)= 38 + 51 (9)

= 38 + 459

= 497

can someone answer this question plz

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
