Explanation
This is an arithmetic sequence with:
General formula for then th term of an arithmetic sequence:
T_n = a + (n - 1)d T n = a + ( n − 1 ) d
We need the 101st term :
T_{101} = 1 + (101 - 1) times 3 = 1 + 100 times 3 = 1 + 300 = boxed{301} T 101 = 1 + ( 101 − 1 ) × 3 = 1 + 100 × 3 = 1 + 300 = 301

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Step 1: Use projectile motion The maximum range of a projectile (ignoring air resistance) is given by:
R =v^ 2 sin ( 2 θ )/ g
The maximum range occurs when θ = 4 5 ∘the value is maximum at (i.e.,sin ( 9 0 ∘ ) = 1 ).
Step 2: Plug in values
v = 12 text{m/s} v = 12 m/s
g = 10 m/s^ 2
R = 1 2^ 2 ⋅ 1 / 10
= 144/10
= 14.4 meters
