Question

Find the second term if a2 =8 and a5= 7 find the 19 term

Answer 1

$<hr color = "grey" width = 80%></hr> <font type = "Quirlycues" size = "4" color = "peach"> Hey frnd..... <hr color = "black" width = 90% ></hr> Given that 2nd term = a+d = 8 5th term = a+4d = 7 now subtract both the equation$
$(a + 4d) - (a + d) = 7 - 8 \\ 3d = 1 \\ d = 1 \div 3$
now putting this value in a+d = 8<br> we get a = 8-1/3 = 23/3
<br> now we know that.... 19th term = a+18d <br>
$23 \div 3 + 18 \times 1 \div 3 \\ 41 \div 3$
so the 19th term = 41/3<br><br>
