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=7
B.f[n]= 4+3n
C. f[n]= 4[3]^n-1
D.f[n]=7[3]^n-1
Answer:
Option B is correct.
Step-by-step explanation:
Given:
The given sequence of an AP is.
7,10,13,16,19......
The first term of an AP 
And common difference 
The function which defined this sequence is;
Now we substitute a and d value in above equation.
therefore, the function for the given sequence for all integers
1 is;
Okay calm down i have the answer, it is point d <span />
Step-by-step explanation:
The derivative of ln(u) is du / u.
d/dx (ln y) = y' / y
