Fill in the blanks in the following table, given that a is the first term, d the common difference and an the nth term of the AP:
Choose the correct choice in the following and justify :
30th term of the AP: 10, 7, 4, . . . , is
(A) 97 (B) 77 (C) –77 (D) – 87
Choose the correct choice in the following and justify :
30th term of the AP: 10, 7, 4, . . . , is
11th term of the A.P. is
In the following APs, find the missing terms in the boxes.
Let the common difference of the given A .P. be d. Then,
Third term = 2 + d + d= 2 + 2d According to the question,
2 + 2d = 26
2d = 26 - 2
2d = 24
So, second term = 2 + d = 2 + 12 = 14.
Hence, the missing termed in the box 14.
