B.f[n]= 4+3n
C. f[n]= 4[3]^n-1
D.f[n]=7[3]^n-1
The correct option is D) f(n) = 4 + 3n.
Step-by-step explanation:
Given :
Arithmetic Sequence -- 7,10,13,16,19
Solution :
The explicit formula of arithmetic sequence is given by,
------- (1)
where, common difference (d) = 10 - 7 = 3
first term (a) = 7
So from equation (1),
Therefore, the correct option is D) f(n) = 4 + 3n.

Answer:
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;
Answer:
22.4

Answer:
18 Runners finished the race
Step-by-step explanation:
Given in question
Number of runners taken part in race = 90
Now in first half , drpped
i.e = 36
so left runners in first half = 90- 36 = 54
again in second half 54 runners are there, but of them again dropped
So, = 36
Thus runner left in second half = 54 -36 = 18
Hence the number of runner finished the race = 18 Answer
Answer:
The value of x i.e DE is
Step-by-step explanation:
Given a parallelogram has sides measuring 23.8 m and 35.3 m. The height corresponding to the 23.8-m base is 9.9 m. we have to find the height corresponding to the 35.3-m base which is DE
Area of parallelogram ABCD=
=
=
Area of parallelogram ABCD=
=
=
Above two is the area of same parallelogram
⇒
⇒
Hence,The value of x i.e DE is
