Find the 43rd term of the sequence?

This is an arithmetic sequence with first term  a1 = 19.5 and common difference d = 0.4

43rd term  = a1 + 42*2

                  =   19.5 + 42*0.4

                  =  36.3  (Answer).

Hello!

If you look at the sequence already, you can tell that the pattern of the sequence is adding 0.4 as adding 0.4 to 19.5 will equal 19.9. Now if you continue to add 0.4 to the sequence, you will find your answer.

19.5, 19.9, 20.3, 20.7, 21.1, 21.5, 21.9, 22.3, 22.7, 23.1, 23.5, 23.9, 24.3, 24.7, 25.1, 25.5, 25.9, 26.3, 26.7, 27.1, 27.5, 27.9, 28.3, 28.7, 29.1, 29.5, 29.9, 30.3, 30.7, 31.1, 31.5, 31.9, 32.3, 32.7, 33.1, 33.5, 33.9, 34.3, 34.7, 35.1, 35.5, 35.9, 36.3...

Once you've completed the sequence, you will see that the 43rd term of the sequence is 36.3.

I hope this helps!
