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!
