Question
Find:
$10^{th}$ term of the A.P. $1, 4, 7, 10, .....$
$10^{th}$ term of the A.P. $1, 4, 7, 10, .....$
✓
Answer
Given A.P. is
$1,4,7,10, \ldots . .$
First term $(a)=1$
Common difference (d) = second term first term
$=4-1$
$=3 .$
$n ^{\text {th }}$ term in an A.P. $= a +( n - a ) d$
$10^{\text {th }}$ term in an $1+(10-1) 3$
$=1+9 \times 3$
$=1+27$
$=28$
