No, it isn't correct. Learn about convergent and divergent series, and which operations are allowed on them. You need to be very careful with convergence issues.

the error is on the part of the two match series with a formula? ( image 2 )

The error is assuming the series converges and thus can be treated as real numbers instead of infinity.
