Question

find the 10th term of the AP :- 2,7,12,...........
​

Answer 1

Step-by-step explanation:

The given AP is 2, 7, 12, .....

Common Difference, d = 5.

First term, a = 2

Hence, 10th term is a+9d = 2+45 = 47.

Answer 2

Answer:

a=2

$\small\sf{d=7-2=5}d=7−2=5$

$\small\sf{n=10}n=10$

━━━━━━━━━━━━━━━

$\small\sf{an=a+(n-1)d}an=a+(n−1)d$

$\small\sf{a10=2+(10-1)5}a10=2+(10−1)5$

$\small\sf{2+45}2+452+452+45$

$\small\sf{47}$

Therefore, the 10th term of the given AP is 47.
