The first five terms of a sequence are 7,10, 13 , 16 and 19. which of the following functions define this sequence for all integers n> or equal to 1? a. f[n]= 3n=7b. f[n]= 4+3nc. f[n]= 4[3]^n-1d. f[n]=7[3]^n-1

Option B is correct

For , the function for the given sequence is defined as;

Step-by-step explanation:

An arithmetic sequence is a sequence in which the difference between each consecutive term is constant.

An explicit formula for this arithmetic sequence given by;

where a represents first term

Since, the given sequences; 7 , 10 , 13 , 16 and 19

⇒ common difference(d) = 3 and a = 7

Since.

10 -7 = 3

13- 10 = 3  ....

The function which defined this sequence is;

using distributive property:

therefore, the function for the given sequence for all integers is;  

good luck!

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
