What is the 12th term of the linear sequence below?
7,9,11,13,15

The 12th term would be 29

Step-by-step explanation:

First find the Algebraic expression:-

Xn = dn + b

'd' means common difference, which is 2 in this sequence.

'b' means 'first term- d'

So, b = 7 - 2

b = 5

Xn = 2n + 5

Now, to find the 12th term, substitute 12 in the place of 'n':-

2 x 12 + 5

29 is the 12th term!

4x and 6y

im not sure though

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
