term is 35. Find the sum of 13 terms of
the sequence.
​

Answer 1

Answer:

Sum of 13 terms is 173

Answer 2

Answer:

Some Important Electricity Formulas are:

I = Q t I = \frac {Q}{t} I=tQ.

V = Q C V =\frac {Q}{C} V=CQ.

R = ρ × l A R = \frac {\rho \times l} {A} R=Aρ×l.

I = V R I= \frac {V}{R} I=RV.

σ = 1 ρ \sigma = \frac{1}{\rho} σ=ρ1.
