Question

The (n + 1)ᵗʰ term of the AP is ​

Answer 1

Answer:

The standard way of solving this is by model long the A.P. as a=12 and d=5 and the. ... nth term of an Arithmetic Progression = (first term+(n–1)*common difference. So (n–1)th term=first term+(n–2)*common difference.

Answer 2

The standard way of solving this is by model long the A.P. as a=12 and d=5 and the. ... nth term of an Arithmetic Progression = (first term+(n–1)*common difference. So (n–1)th term=first term+(n–2)*common difference.

Hint: Use the fact that if a is the first term of an A.P and d is the common difference of the A.P, then the nth term of the A.P is given by an=a+(n−1)d. ... Here the A.P is 7, 12 , 17, 22, … Hence, the first term of the A.P is 7 and the common difference of the A.P is 12-7 = 5. Hence, we have a= 7 and d = 5.
