"one less than the product of a number and 3 is 5 more than the number itself"

Mathematics
1 answer:
Andrej [43]3 years ago
4 0

Answer:

  the number is 3

Step-by-step explanation:

Perhaps you'd like to find the number.

If n represents the number, we can write the relationship as ...

  3n -1 = n +5

Adding 1-n to both sides gives ...

  2n = 6

  n = 3 . . . . divide by 2

The number is 3.

_____

<em>Check</em>

The product of the number and 3 is 9. One less is 8. That is 5 more than the number itself: 8 = 3 + 5.

What is the explict rule for the sequence 12,22,32,42​
icang [17]

The explicit rule for given sequence is:

a_n=2+10n

Further explanation:

We have to determine first of all if the sequence is arithmetic or geometric.

  • If the difference of two consecutive terms is same then the sequence is arithmetic sequence
  • If the ratio of two consecutive terms is same then the sequence is geometric sequence

Given sequence is:

12,22,32,42​

a_1=12\\a_2=22\\a_3=32\\.......\\Let\\d=Common\ difference\\d=a_2-a_1=22-12=10\\d=a_3-a_2=32-22=10

The common difference is 10 which is same for all consecutive terms. So the sequence is an arithmetic sequence.

The general formula for arithmetic sequence is:

a_n=a_1+(n-1)d\\Here,\\a_n\ is\ the\ nth\ term\\a_1\ is\ the\ first\ term\\d\ is\ the\ common\ difference

Putting the values of a1 and d

a_n= 12+(n-1)(10)\\a_n=12+10n-10\\a_n=2+10n

The explicit rule for given sequence is:

a_n=2+10n
