Question

If
-5
7
a, 2 are consecutive terms in an Arthimetic Progression, then
the value of ‘a' is

Answer 1

Answer:

Value of of a is 2...........

Answer 2

/* There is a mistake in the question. It must be like this */

$Given \: -5 , 7, a , 31 \: are \: consecutive \\terms \: in \: an \: Arithmetic \: Progression$

$First \: term ( a = a_{1} ) = -5$

$Common \: difference (d) \\= a_{2} - a_{1} \\= 7 - (-5) \\= 7 + 5 \\= 12$

$\red{ Third \: term\: (a) } \\= a_{2}+d \\= 7 + 12 \\= 19$

Therefore.,

$\red{ Value \:of \: a }\green { = 19}$
