Question

write the 26 th term of the ap 7 ,4 ,1, -2​

Answer 1

Answer:

here,

a=7

d=-3

n=26

now ,

a n= a+(n-1)d

=7+(26-1)-3

=7+25×(-3)

=7-75

=-68

Answer 2

AnswEr:

26th Term of the AP is -68.

Step By Step Explanation:-

Given:-

First Term (a) = 7

Common Difference = $\sf\; a_2 \; - \; a_1$

$:\implies\sf\; 7 \; - \; 4$

$:\implies\large\boxed{\sf{\red{d = -3}}}$

Finding term:-

We know that,

$\large{\underline{\boxed{\sf{\red{an \; = \; a \; + \; (n \; - \; 1)d}}}}}$

$\diamond\bold{\underline{\sf{Putting\; Values}}}$

$:\implies\sf\; an = 7 + (26 - 1)(-3)$

$:\implies\sf\; an = 7 + 25 \times \; -3$

$:\implies\sf\; an = 7 - 75$

$:\implies\large{\underline{\boxed{\sf{\pink{an \; = \; -68}}}}}$

$\bold{\underline{\sf{Hence,\; 26th\; term \; of \; the \; AP \; is \; -68.}}}$
