Question

first term and common difference of ana.p are 6and3 respectively find 27​

Answer 1

Given

we have given first term (a) = 6

common difference (d) = 3

To Find

We have to find 27th term of an ap

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

Formula used here :

aₙ= a+(n-1)d

27th term can be written as

a₂₇= a+(27-1)d

a₂₇= a+26d

Now,put the values :

a= 6 & d = 3

a₂₇= a+26d

a₂₇= 6+26(3)

a₂₇= 6+78

a₂₇= 84

hence ,27th term is 84

Extra information=>

$\:\:\:\:\:\:$If a,a₂,a₃,a₄,are in ap

then find sum

sₙ=n/2(2a+(n-1)d

$\:\:\:\:\:\:$If a,a₂,a₃,a₄,are in ap

then find the common difference

d= second term(a₂) -first term(a)
