Answer 1

$\huge\underline\mathrm{Question}:-$

Find the 10th term of the AP 2,7,1,2.....

$\huge\underline\mathrm{Solution}:-$

Here, First term, a = 2

Common Difference = a2 - a1

=> 7 - 2 = 5

=> d = 5

By using the formula, an = a + (n-1)d

Putting Values:-

=> an = 2 + (10 - 1)(5)

=> an = 2 + (10 - 1)(5)

=> an = 2 + 9 × 5

=> an = 46

10th term of the AP will be 46
