Ana wants to find the fifth term of a sequence -12, -7, -2, 3 witch concept will you suggest to be used a. geometric sequence
b. fibonacci
c. arithmetic sequence
d. harmonic

Ana should use Arithmetic sequence because in this sequence there is successive addition of 5.

so,

5th term = a + (5 - 1)d

where, a is the first term, and d is the common difference.

a = -12 ( first term )

d = 5 ( -7 - (-12 ) = -7 + 12 = 5 )

so,

5th term :

=》 -12 + (5 - 1)5

=》 -12 + (4 × 5)

=》 -12 + 20

=》 8

hence, 50 th tem of the sequence is 8

Arithmetic sequence

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

answer: h
