It is A.P. with common difference = 2.54-1.31 = 1.23

So, next term would be 3.77+1.23 = 5.00

OPTION B IS YOUR ANSWER

Answer:

Option B is correct.

the next term of the sequence is 5.00

Explanation:

Arithmetic progression(A.P) is a sequence of numbers in which the consecutive terms are formed by adding a constant quantity with the preceding term.


Common difference(d) is the constant quantity stated in the above definition of arithmetic progression. it is given by;

[tex]d=a_{n+1} - a_n[/tex] for all n∈N


Given sequence:-  1.31, 2.54 , 3.77 , ___ ;

we have;

[tex]a_1 = 1.31[/tex] , [tex]a_2= 2.54[/tex] and  [tex]a_3 = 3.77[/tex]

First find the common difference;

[tex]d =a_2 - a_1[/tex] = [tex]2.54-1.31 = 1.23[/tex]

or

d = [tex]=a_3-a_2 = 3.77-2.54 =1.23[/tex]

Therefore, by the definition of arithmetic progression,

the given sequence is Arithmetic progression

Now, to find the fourth term of the sequence, add constant quantity (d) to the third term;

[tex]a_4 = 3.77+1.23 = 5.00[/tex]

Therefore, in the given sequence next term will be 5.00.
