Answer 2

$\huge{\star{\sf{\underline{Given :}}}}$

• A.P : 80, 81, 82, ........ 136
• First term (a) = 80
• Common Difference (d) = 1
• Last term (Aₙ) = 136

$\huge{\star{\sf{\underline{To \: Find :}}}}$

We have to find the number of terms (n) in the A.P.

$\huge{\star{\sf{\underline{Solution :}}}}$

We know that,

$\large{\implies{\underline{\boxed{\sf{A_n = a + (n - 1)d}}}}} \\ \\ \sf{\dashrightarrow 136 = 80 + (n - 1)1} \\ \\ \sf{\dashrightarrow 136 = 80 + n - 1} \\ \\ \sf{\dashrightarrow 136 = 79 + n} \\ \\ \sf{\dashrightarrow n = 136 - 79} \\ \\ \sf{\dashrightarrow n = 57} \\ \\ \large{\implies{\underline{\boxed{\sf{n = 57}}}}}$

∴ Number of terms (n) in the A.P i 57.
