10th term of the progression -4-1+2+5+------------

Dear jayku kumar,

The Formula for finding the n^th term in Arithmetic Progression is given by

a_n = a₁ + (n-1)d

where,

a_n is the value of the n^th term

a₁ is the value of the first term

n is the n^th term

d is the difference 

In this case, a₁ = -4, d = (a₂ -a₁) = 3, n=10

Therefore substituting these values,we get the value of the n^th term(a_n)

Therefore, a_n = -4 + (10-1)3

                   = -4 +(9)3

                   = -4+ 27

                   = 23

Hence the 10^th term is 23.

Hope this helped you immensely...!!

All the Very Best & Good Luck to you ...!!

Please approve my answer if you liked it by clicking on "Yes" given below..!!

the given sequence is an AP with a₁= -4 and d= 3. We have find out the 10th term of this sequence.

So a_n = a₁ + (n-1)d. Here n=10. 

So a₁₀= -4 + 9×3 =23

Hence the 10th term of this sequence is 23
